99-630: Following the American Civil War , the United States Veterans Signal Association was formed from the original Signal Corps established under Maj. Albert J. Myer of the U.S. Army . This organization was active for many years, ultimately being augmented by veterans from the Spanish–American War and World War I . The American Signal Corps Association, another World War I group, merged with

198-522: A Baltimore newspaper editor, Frank Key Howard , after he criticized Lincoln in an editorial for ignoring Taney's ruling. In Missouri, an elected convention on secession voted to remain in the Union. When pro-Confederate Governor Claiborne Fox Jackson called out the state militia, it was attacked by federal forces under General Nathaniel Lyon , who chased the governor and rest of the State Guard to

297-838: A Call For Papers (CFP) or a Call For Abstracts, which is sent to prospective presenters and explains how to submit their abstracts or papers. It describes the broad theme and lists the meeting's topics and formalities such as what kind of abstract (summary) or paper has to be submitted, to whom, and by what deadline . A CFP is usually distributed using a mailing list or on specialized online services. Contributions are usually submitted using an online abstract or paper management service. Predatory conferences or predatory meetings are meetings set up to appear as legitimate scientific conferences but which are exploitative as they do not provide proper editorial control over presentations, and advertising can include claims of involvement of prominent academics who are, in fact, uninvolved. They are an expansion of

396-525: A blockade of the Confederacy to suffocate the South into surrender. Lincoln adopted parts of the plan but opted for a more active war strategy. In April 1861, Lincoln announced a blockade of all Southern ports; commercial ships could not get insurance, ending regular traffic. The South blundered by embargoing cotton exports before the blockade was fully effective; by the time they reversed this decision, it

495-410: A conference is performed by active RFID that may indicate wilfully identified and relatively located upon approach via electronic tags. Conferences are usually organized either by a scientific society or by a group of researchers with a common interest. Larger meetings may be handled on behalf of the scientific society by a Professional Conference Organiser or PCO. The meeting is announced by way of

594-497: A course of ultimate extinction. Decades of controversy over slavery were brought to a head when Abraham Lincoln , who opposed slavery's expansion, won the 1860 presidential election . Seven Southern slave states responded to Lincoln's victory by seceding from the United States and forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. The war began on April 12, 1861, when

693-705: A draft law in April 1862 for men aged 18–35, with exemptions for overseers, government officials, and clergymen. The U.S. Congress followed in July, authorizing a militia draft within states that could not meet their quota with volunteers. European immigrants joined the Union Army in large numbers, including 177,000 born in Germany and 144,000 in Ireland. About 50,000 Canadians served, around 2,500 of whom were black. When

792-483: A firm hand by Lincoln tamed Seward, who was a staunch Lincoln ally. Lincoln decided holding the fort, which would require reinforcing it, was the only workable option. On April 6, Lincoln informed the Governor of South Carolina that a ship with food but no ammunition would attempt to supply the fort. Historian McPherson describes this win-win approach as "the first sign of the mastery that would mark Lincoln's presidency";

891-479: A man until she died in 1915 at the age of 71. The small U.S. Navy of 1861 rapidly expanded to 6,000 officers and 45,000 sailors by 1865, with 671 vessels totaling 510,396 tons. Its mission was to blockade Confederate ports, control the river system, defend against Confederate raiders on the high seas, and be ready for a possible war with the British Royal Navy . The main riverine war was fought in

990-451: A patriotic fire under the North. On April 15, Lincoln called on the states to field 75,000 volunteer troops for 90 days; impassioned Union states met the quotas quickly. On May 3, 1861, Lincoln called for an additional 42,000 volunteers for three years. Shortly after this, Virginia , Tennessee , Arkansas , and North Carolina seceded and joined the Confederacy. To reward Virginia,

1089-421: A republic, but a third challenge faced the nation: maintaining a republic based on the people's vote, in the face of an attempt to destroy it. Lincoln's election provoked South Carolina 's legislature to call a state convention to consider secession. South Carolina had done more than any other state to advance the notion that a state had the right to nullify federal laws and even secede. On December 20, 1860,

1188-436: A short abstract of their presentation, which will be reviewed before the presentation is accepted for the meeting. Some organizers, and therefore disciplines require presenters to submit a paper, which is peer reviewed by members of the program committee or referees chosen by them. In some disciplines, such as English and other languages, it is common for presenters to read from a prepared script. In other disciplines such as

1287-433: Is a mix of pre-recorded and live presentations. Because virtual or hybrid events allow people from different time zones to participate simultaneously, some will have to participate during their night-time. Some virtual conferences try to mitigate this issue by alternating their schedule in a way so that everyone has the chance to participate at day time at least once. Prospective presenters are usually asked to submit

In addition, information in this directory also is available according to corporate focus categories in the Cybersecurity, Intelligence, Health IT, Education and Homeland Security directories. Organizations provide

1485-490: The 1860 presidential election . Southern leaders feared Lincoln would stop slavery's expansion and put it on a course toward extinction. His victory triggered declarations of secession by seven slave states of the Deep South , all of whose riverfront or coastal economies were based on cotton that was cultivated by slave labor. Lincoln was not inaugurated until March 4, 1861, giving the South time to prepare for war during

1584-541: The Battle of Appomattox Court House , setting in motion the end of the war . Lincoln led the nation through that victory but was shot by an assassin on April 14. By the end of the war, much of the South's infrastructure was destroyed. The Confederacy collapsed, slavery was abolished, and four million enslaved black people were freed. The war-torn nation then entered the Reconstruction era in an attempt to rebuild

1683-689: The Dred Scott decision was proof the Southern states had no reason to secede and that the Union "was intended to be perpetual". He added, however, that "The power by force of arms to compel a State to remain in the Union" was not among the "enumerated powers granted to Congress". A quarter of the US army—the Texas garrison—was surrendered in February to state forces by its general, David E. Twiggs , who joined

1782-618: The Emancipation Proclamation went into effect in January 1863, ex-slaves were energetically recruited to meet state quotas. States and local communities offered higher cash bonuses for white volunteers. Congress tightened the draft law in March 1863. Men selected in the draft could provide substitutes or, until mid-1864, pay commutation money. Many eligibles pooled their money to cover the cost of anyone drafted. Families used

1881-592: The Virginia to prevent its capture, while the Union built many copies of the Monitor . The Confederacy's efforts to obtain warships from Great Britain failed, as Britain had no interest in selling warships to a nation at war with a stronger enemy and feared souring relations with the U.S. By early 1861, General Winfield Scott had devised the Anaconda Plan to win the war with minimal bloodshed, calling for

1980-522: The Western theater , the Union made permanent gains—though in the Eastern theater the conflict was inconclusive. The abolition of slavery became a Union war goal on January 1, 1863, when Lincoln issued the Emancipation Proclamation , which declared all slaves in rebel states to be free, applying to more than 3.5 million of the 4 million enslaved people in the country. To the west, the Union first destroyed

2079-526: The electrical telegraph , steamships, the ironclad warship , and mass-produced weapons were widely used. The war left an estimated 698,000 soldiers dead, along with an undetermined number of civilian casualties, making the Civil War the deadliest military conflict in American history. The technology and brutality of the Civil War foreshadowed the coming World Wars . The origins of the war were rooted in

2178-461: The predatory publishing business model, which involves the creation of academic publications built around an exploitative business model that generally involves charging publication fees to authors without providing the editorial and publishing services associated with legitimate journals. BIT Life Sciences and SCIgen are some of the conferences labeled as predatory. Academic conferences are criticized for being environmentally unfriendly, due to

2277-424: The sciences , presenters usually base their talk around a visual presentation that displays key figures and research results. A large meeting will usually be called a conference, while a smaller is termed a workshop. They might be single track or multiple track , where the former has only one session at a time, while a multiple track meeting has several parallel sessions with speakers in separate rooms speaking at

2376-406: The 168,649 men procured for the Union through the draft, 117,986 were substitutes, leaving only 50,663 who were conscripted. In the North and South, draft laws were highly unpopular. In the North, some 120,000 men evaded conscription, many fleeing to Canada, and another 280,000 soldiers deserted during the war. At least 100,000 Southerners deserted, about 10 percent of the total. Southern desertion

2475-672: The Armed Forces Communications and Electronics Association. In 1979, the Armed Forces Communications and Electronics Association became international with the establishment of chapters in Europe , Asia and Canada . On October 1, 2018, the organization's name was shortened to AFCEA International. SIGNAL, not to be confused with the German Signal magazine, is a monthly international news magazine targeting government, military and industry professionals active in

2574-601: The Atlantic and Pacific oceans. Insurance rates soared, and the American flag virtually disappeared from international waters, though reflagging ships with European flags allowed them to continue operating unmolested. After the war, the U.S. government demanded Britain compensate it for the damage caused by blockade runners and raiders outfitted in British ports. Britain paid the U.S. $ 15 million in 1871, but only for commerce raiding. Dinçaslan argues that another outcome of

2673-566: The Bahamas in exchange for high-priced cotton. Many were lightweight and designed for speed, only carrying small amounts of cotton back to England. When the Union Navy seized a blockade runner, the ship and cargo were condemned as a prize of war and sold, with proceeds given to the Navy sailors; the captured crewmen, mostly British, were released. The Southern economy nearly collapsed during

2772-400: The British response to the U.S. was toned down, helping avert war. In 1862, the British government considered mediating between the Union and Confederacy, though such an offer would have risked war with the U.S. British Prime Minister Lord Palmerston reportedly read Uncle Tom's Cabin three times when deciding what his decision would be. The Union victory at the Battle of Antietam caused

2871-621: The British to delay this decision. The Emancipation Proclamation increased the political liability of supporting the Confederacy. Realizing that Washington could not intervene in Mexico as long as the Confederacy controlled Texas, France invaded Mexico in 1861 and installed the Habsburg Austrian archduke Maximilian I as emperor. Washington repeatedly protested France's violation of the Monroe Doctrine . Despite sympathy for

2970-575: The Commonwealth, which at its greatest extent was over half the state, and it went into exile after October 1862. After Virginia's secession, a Unionist government in Wheeling asked 48 counties to vote on an ordinance to create a new state in October 1861. A voter turnout of 34% approved the statehood bill (96% approving). Twenty-four secessionist counties were included in the new state, and

3069-486: The Confederacy bombarded Fort Sumter in South Carolina . A wave of enthusiasm for war swept over the North and South, as military recruitment soared. Four more Southern states seceded after the war began and, led by its president, Jefferson Davis , the Confederacy asserted control over a third of the U.S. population in eleven states. Four years of intense combat, mostly in the South, ensued. During 1861–1862 in

3168-400: The Confederacy refused to exchange black prisoners. After that, about 56,000 of the 409,000 POWs died in prisons, accounting for 10 percent of the conflict's fatalities. Historian Elizabeth D. Leonard writes that between 500 and 1,000 women enlisted as soldiers on both sides, disguised as men. Women also served as spies, resistance activists, nurses, and hospital personnel. Women served on

3267-539: The Confederacy's river navy by the summer of 1862, then much of its western armies, and seized New Orleans . The successful 1863 Union siege of Vicksburg split the Confederacy in two at the Mississippi River , while Confederate General Robert E. Lee 's incursion north failed at the Battle of Gettysburg . Western successes led to General Ulysses S. Grant 's command of all Union armies in 1864. Inflicting an ever-tightening naval blockade of Confederate ports,

3366-518: The Confederacy, France's seizure of Mexico ultimately deterred it from war with the Union. Confederate offers late in the war to end slavery in return for diplomatic recognition were not seriously considered by London or Paris. After 1863, the Polish revolt against Russia further distracted the European powers and ensured they remained neutral. Russia supported the Union, largely because it believed

3465-706: The Confederacy. As Southerners resigned their Senate and House seats, Republicans could pass projects that had been blocked. These included the Morrill Tariff , land grant colleges, a Homestead Act , a transcontinental railroad, the National Bank Act , authorization of United States Notes by the Legal Tender Act of 1862 , and the end of slavery in the District of Columbia . The Revenue Act of 1861 introduced income tax to help finance

3564-755: The Confederate capital was moved to Richmond . Maryland , Delaware , Missouri , West Virginia and Kentucky were slave states whose people had divided loyalties to Northern and Southern businesses and family members. Some men enlisted in the Union Army and others in the Confederate Army. West Virginia separated from Virginia and was admitted to the Union on June 20, 1863, though half its counties were secessionist. Maryland's territory surrounded Washington, D.C. , and could cut it off from

3663-542: The District of Columbia by seizing prominent figures, including arresting one-third of the members of the Maryland General Assembly on the day it reconvened. All were held without trial, with Lincoln ignoring a ruling on June 1, 1861, by Supreme Court Chief Justice Roger Taney , not speaking for the Court, that only Congress could suspend habeas corpus ( Ex parte Merryman ). Federal troops imprisoned

3762-479: The North, where anti-slavery sentiment had grown, and for the South, where the fear of slavery's abolition had grown. Another factor leading to secession and the formation of the Confederacy was the development of white Southern nationalism in the preceding decades. The primary reason for the North to reject secession was to preserve the Union, a cause based on American nationalism . Background factors in

3861-658: The North. It had anti-Lincoln officials who tolerated anti-army rioting in Baltimore and the burning of bridges, both aimed at hindering the passage of troops to the South. Maryland's legislature voted overwhelmingly to stay in the Union, but rejected hostilities with its southern neighbors, voting to close Maryland's rail lines to prevent their use for war. Lincoln responded by establishing martial law and unilaterally suspending habeas corpus in Maryland, along with sending in militia units. Lincoln took control of Maryland and

3960-461: The South's post-war recovery. Cotton diplomacy proved a failure as Europe had a surplus of cotton, while the 1860–62 crop failures in Europe made the North's grain exports critically important. It also helped turn European opinion against the Confederacy. It was said that "King Corn was more powerful than King Cotton," as U.S. grain went from a quarter to almost half of British imports. Meanwhile,

4059-545: The South. The Confederacy turned to foreign sources, connecting with financiers and companies like S. Isaac, Campbell & Company and the London Armoury Company in Britain, becoming the Confederacy's main source of arms. To transport arms safely to the Confederacy, British investors built small, fast, steam-driven blockade runners that traded arms and supplies from Britain, through Bermuda, Cuba, and

4158-575: The U.S. Veterans Signal Association in 1918 and was active until 1944 ( World War II ). In May 1946, Maj. Gen. Harry C. Ingles, Brig. Gen. David Sarnoff , and a number of industry leaders joined to found the Army Signal Association, absorbing the remaining chapters of its predecessors. In 1947, the name was changed to the Armed Forces Communications Association, and in 1954 the name evolved as

4257-500: The U.S. and Britain over the Trent affair , which began when U.S. Navy personnel boarded the British ship Trent and seized two Confederate diplomats. However, London and Washington smoothed this over after Lincoln released the two men. Prince Albert left his deathbed to issue diplomatic instructions to Lord Lyons during the Trent affair. His request was honored, and, as a result,

4356-892: The U.S. served as a counterbalance to its geopolitical rival, the U.K. In 1863, the Imperial Russian Navy 's Baltic and Pacific fleets wintered in the American ports of New York and San Francisco, respectively. Academic conference An academic conference or scientific conference (also congress , symposium , workshop , or meeting ) is an event for researchers (not necessarily academics ) to present and discuss their scholarly work. Together with academic or scientific journals and preprint archives, conferences provide an important channel for exchange of information between researchers. Further benefits of participating in academic conferences include learning effects in terms of presentation skills and "academic habitus ", receiving feedback from peers for one's own research,

4455-471: The Union Army or pro-Union guerrilla groups. Although they came from all classes, most Southern Unionists differed socially, culturally, and economically from their region’s dominant prewar, slave-owning planter class. At the war's start, a parole system operated, under which captives agreed not to fight until exchanged. They were held in camps run by their army, paid, but not allowed to perform any military duties. The system of exchanges collapsed in 1863 when

4554-456: The Union blockade. The Confederacy purchased warships from commercial shipbuilders in Britain, with the most famous being the CSS ; Alabama , which caused considerable damage and led to serious postwar disputes . However, public opinion against slavery in Britain created a political liability for politicians, where the anti-slavery movement was powerful. War loomed in late 1861 between

4653-464: The Union hospital ship Red Rover and nursed Union and Confederate troops at field hospitals. Mary Edwards Walker , the only woman ever to receive the Medal of Honor , served in the Union Army and was given the medal for treating the wounded during the war. One woman, Jennie Hodgers, fought for the Union under the name Albert D. J. Cashier. After she returned to civilian life, she continued to live as

4752-484: The Union marshaled resources and manpower to attack the Confederacy from all directions. This led to the fall of Atlanta in 1864 to Union General William Tecumseh Sherman , followed by his March to the Sea . The last significant battles raged around the ten-month Siege of Petersburg , gateway to the Confederate capital of Richmond . The Confederates abandoned Richmond, and on April 9, 1865, Lee surrendered to Grant following

4851-492: The Union would win if it could resupply and hold the fort, and the South would be the aggressor if it opened fire on an unarmed ship supplying starving men. An April 9 Confederate cabinet meeting resulted in Davis ordering General P. G. T. Beauregard to take the fort before supplies reached it. At 4:30 am on April 12, Confederate forces fired the first of 4,000 shells at the fort; it fell the next day. The loss of Fort Sumter lit

4950-433: The Union, this was never likely, so they sought to bring them in as mediators. The Union worked to block this and threatened war if any country recognized the Confederacy. In 1861, Southerners voluntarily embargoed cotton shipments, hoping to start an economic depression in Europe that would force Britain to enter the war, but this failed. Worse, Europe turned to Egypt and India for cotton, which they found superior, hindering

5049-483: The Union-held Fort Sumter. Fort Sumter is located in the harbor of Charleston , South Carolina. Its status had been contentious for months. Outgoing President Buchanan had dithered in reinforcing its garrison, commanded by Major Robert Anderson . Anderson took matters into his own hands and on December 26, 1860, under the cover of darkness, sailed the garrison from the poorly placed Fort Moultrie to

5148-702: The Union. A February peace conference met in Washington, proposing a solution similar the Compromise; it was rejected by Congress. The Republicans proposed the Corwin Amendment , an alternative, not to interfere with slavery where it existed, but the South regarded it as insufficient. The remaining eight slave states rejected pleas to join the Confederacy, following a no-vote in Virginia's First Secessionist Convention on April 4. On March 4, Lincoln

5247-577: The West, where major rivers gave access to the Confederate heartland. The U.S. Navy eventually controlled the Red, Tennessee, Cumberland, Mississippi, and Ohio rivers. In the East, the Navy shelled Confederate forts and supported coastal army operations. The Civil War occurred during the early stages of the industrial revolution, leading to naval innovations, notably the ironclad warship . The Confederacy, recognizing

5346-579: The Western territories destined to become states. Initially Congress had admitted new states into the Union in pairs, one slave and one free . This had kept a sectional balance in the Senate but not in the House of Representatives , as free states outstripped slave states in numbers of eligible voters. Thus, at mid-19th century, the free-versus-slave status of the new territories was a critical issue, both for

5445-711: The amount of airplane traffic generated by them. A correspondence on Nature.com points out the "paradox of needing to fly to conferences" despite increased calls for sustainability by environmental scientists. The academic community's carbon footprint is comprised in large parts by emissions caused by air travel. Few conferences enacted practices to reduce their environmental impact by 2017, despite guidelines being widely available: An analysis of academic conferences taking place in 2016 showed that only 4% of 116 conferences sampled offered carbon offset options and only 9% of these conferences implemented any form of action to their reduce environmental impact. More conferences included

5544-521: The blockade was the rise of oil as a prominent commodity. The declining whale oil industry took a blow as many old whaling ships were used in blockade efforts, such as the Stone Fleet , and Confederate raiders harassed Union whalers. Oil products, especially kerosene, began replacing whale oil in lamps, increasing oil's importance long before it became fuel for combustion engines. Although the Confederacy hoped Britain and France would join them against

5643-695: The classroom and online. Through leadership development, education, events, and networking, the association helps women advance in their careers. The Emerging Professionals in Intelligence Community (EPIC) Committee enables young professionals to learn about the various aspects in this specialty field. Through the Small Business Committee and several focused events, the association provides strategies and programs about business processes, upcoming contracts and marketing. AFCEA has more than 130 chapters and sub-chapters around

5742-516: The conference proceedings . Usually a conference will include keynote speakers (often, scholars of some standing, but sometimes individuals from outside academia). The keynote lecture is often longer, lasting sometimes up to an hour and a half, particularly if there are several keynote speakers on a panel . In addition to presentations, conferences also feature panel discussions , round tables on various issues, poster sessions and workshops. Some conferences take more interactive formats, such as

5841-508: The convention unanimously voted to secede and adopted a secession declaration . It argued for states' rights for slave owners but complained about states' rights in the North in the form of resistance to the federal Fugitive Slave Act, claiming that Northern states were not fulfilling their obligations to assist in the return of fugitive slaves. The "cotton states" of Mississippi , Florida , Alabama , Georgia , Louisiana , and Texas followed suit, seceding in January and February 1861. Among

5940-489: The country, bring the former Confederate states back into the United States, and grant civil rights to freed slaves. The war is one of the most extensively studied and written about episodes in U.S. history . It remains the subject of cultural and historiographical debate . Of continuing interest is the fading myth of the Lost Cause of the Confederacy . The war was among the first to use industrial warfare . Railroads,

6039-477: The crisis was Secretary of State William H. Seward , who had been Lincoln's rival for the Republican nomination . Embittered by his defeat, Seward agreed to support Lincoln's candidacy only after he was guaranteed the executive office then considered the second most powerful. In the early stages of Lincoln's presidency Seward held little regard for him, due to his perceived inexperience. Seward viewed himself as

6138-657: The de facto head of government, the " prime minister " behind the throne. Seward attempted to engage in unauthorized and indirect negotiations that failed. Lincoln was determined to hold all remaining Union-occupied forts in the Confederacy: Fort Monroe in Virginia, Fort Pickens , Fort Jefferson , and Fort Taylor in Florida, and Fort Sumter in South Carolina. The American Civil War began on April 12, 1861, when Confederate forces opened fire on

6237-529: The desire of the Southern states to preserve the institution of slavery . Historians in the 21st century overwhelmingly agree on the centrality of slavery in the conflict. They disagree on which aspects (ideological, economic, political, or social) were most important, and on the North 's reasons for refusing to allow the Southern states to secede. The pseudo-historical Lost Cause ideology denies that slavery

6336-493: The ensuing guerrilla war engaged about 40,000 federal troops for much of the war. Congress admitted West Virginia to the Union on June 20, 1863. West Virginians provided about 20,000 soldiers to each side in the war. A Unionist secession attempt occurred in East Tennessee , but was suppressed by the Confederacy, which arrested over 3,000 men suspected of loyalty to the Union; they were held without trial. The Civil War

6435-430: The essential role of cotton in the European economy. The European aristocracy was "absolutely gleeful in pronouncing the American debacle as proof that the entire experiment in popular government had failed. European government leaders welcomed the fragmentation of the ascendant American Republic." However, a European public with liberal sensibilities remained, which the U.S. sought to appeal to by building connections with

AFCEA's Professional Development provides a wide range of programs of continuing education, leadership development and technical training courses. Courses are available for presentation on-site at organizations' facilities. In addition, some sessions at AFCEA conferences and chapter events qualify as continuing education to maintain cybersecurity certifications. The association also has partnerships with several higher education institutions that offer members discounts on tuition both in

6633-439: The homefront economy could no longer supply. Surdam contends that the blockade was a powerful weapon that eventually ruined the Southern economy, costing few lives in combat. The Confederate cotton crop became nearly useless, cutting off the Confederacy's primary income source. Critical imports were scarce, and coastal trade largely ended as well. The blockade's success was not measured by the few ships that slipped through but by

6732-843: The information in these online publications, including contacts, business focus, products/services, and/or clients. AFCEA is involved in additional communications technologies, including webinars, podcasts, blogs, and RSS Feeds. AFCEA has a presence in social media platforms. The association, in partnership with the AFCEA Educational Foundation, chapters and members, presents $ 2 million annually in scholarships, grants and awards in six categories: college students with science, technology, engineering and mathematics (STEM) majors; current and future teachers of STEM subjects in U.S. middle and high schools; underserved/minority college students studying STEM fields; students in fields related to security such as intelligence, cyber and homeland security; ROTC cadets/midshipmen and military personnel; and students attending

Among the topics covered in the magazine are command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR); information security ; cybersecurity ; research and development; artificial intelligence , machine learning , big data , cloud technologies , electronics ; and homeland security . A monthly online newsletter, SIGNAL Connections ,

6930-482: The international press. By 1861, Union diplomats like Carl Schurz realized emphasizing the war against slavery was the Union's most effective moral asset in swaying European public opinion. Seward was concerned an overly radical case for reunification would distress European merchants with cotton interests; even so, he supported a widespread campaign of public diplomacy. U.S. minister to Britain Charles Francis Adams proved adept and convinced Britain not to challenge

7029-467: The movement to abolish slavery and its influence over the North. Southern states believed that the Fugitive Slave Clause made slaveholding a constitutional right. These states agreed to form a new federal government, the Confederate States of America , on February 4, 1861. They took control of federal forts and other properties within their boundaries, with little resistance from outgoing President James Buchanan , whose term ended on March 4. Buchanan said

7128-476: The need to counter the Union's naval superiority, built or converted over 130 vessels, including 26 ironclads. Despite these efforts, Confederate ships were largely unsuccessful against Union ironclads. The Union Navy used timberclads, tinclads, and armored gunboats. Shipyards in Cairo, Illinois, and St. Louis built or modified steamboats . The Confederacy experimented with the submarine CSS  Hunley , which

7227-418: The new Confederacy sent delegates to Washington to negotiate a peace treaty. Lincoln rejected negotiations, because he claimed that the Confederacy was not a legitimate government and to make a treaty with it would recognize it as such. Lincoln instead attempted to negotiate directly with the governors of seceded states, whose administrations he continued to recognize. Complicating Lincoln's attempts to defuse

7326-417: The ordinances of secession, those of Texas, Alabama, and Virginia mentioned the plight of the "slaveholding states" at the hands of Northern abolitionists. The rest made no mention of slavery but were brief announcements by the legislatures of the dissolution of ties to the Union. However, at least four—South Carolina, Mississippi, Georgia, and Texas —provided detailed reasons for their secession, all blaming

7425-543: The participant driven " unconference " or various conversational formats. Academic conferences have been held in three general formats: in-person, virtual or online and hybrid (in-person and virtual). Conferences have traditionally been organized in-person. Since the COVID-19 pandemic many conferences have either temporarily or permanently switched to a virtual or hybrid format. Some virtual conferences involve both asynchronous and synchronous formats. For example, there

Conferences usually encompass various presentations . They tend to be short and concise, with a time span of about 10 to 30 minutes; presentations are usually followed by a discussion . The work may be bundled in written form as academic papers and published as

7623-489: The program. Business meetings for learned societies , interest groups , or affinity groups can also be part of the conference activities. Academic conferences typically fall into three categories: Increasing numbers of amplified conferences are being provided which exploit the potential of WiFi networks and mobile devices in order to enable remote participants to contribute to discussions and listen to ideas. Advanced technology for meeting with any yet unknown person in

7722-427: The run up to the Civil War were partisan politics , abolitionism , nullification versus secession , Southern and Northern nationalism, expansionism , economics , and modernization in the antebellum period . As a panel of historians emphasized in 2011, "while slavery and its various and multifaceted discontents were the primary cause of disunion, it was disunion itself that sparked the war." Abraham Lincoln won

7821-489: The same time. However, there are no commonly shared definitions even within disciplines for each event type. There might be no conceivable difference between a symposium, a congress or a conference. The larger the conference, the more likely it is that academic publishing houses may set up displays. Large conferences also may have a career and job search and interview activities. At some conferences, social or entertainment activities such as tours and receptions can be part of

7920-636: The southwestern corner of Missouri (see Missouri secession ). Early in the war the Confederacy controlled southern Missouri through the Confederate government of Missouri but was driven out after 1862. In the resulting vacuum, the convention on secession reconvened and took power as the Unionist provisional government of Missouri. Kentucky did not secede, it declared itself neutral. When Confederate forces entered in September 1861, neutrality ended and

8019-532: The stalwart island Fort Sumter. Anderson's actions catapulted him to hero status in the North. An attempt to resupply the fort on January 9, 1861, failed and nearly started the war then, but an informal truce held. On March 5, Lincoln was informed the fort was low on supplies. Fort Sumter proved a key challenge to Lincoln's administration. Back-channel dealing by Seward with the Confederates undermined Lincoln's decision-making; Seward wanted to pull out. But

8118-446: The state reaffirmed its Union status while maintaining slavery. During an invasion by Confederate forces in 1861, Confederate sympathizers and delegates from 68 Kentucky counties organized the secession Russellville Convention, formed the shadow Confederate Government of Kentucky , inaugurated a governor, and Kentucky was admitted into the Confederacy on December 10, 1861. Its jurisdiction extended only as far as Confederate battle lines in

8217-457: The substitute provision to select which man should go into the army and which should stay home. There was much evasion and resistance to the draft, especially in Catholic areas. The New York City draft riots in July 1863 involved Irish immigrants who had been signed up as citizens to swell the vote of the city's Democratic political machine , not realizing it made them liable for the draft. Of

8316-451: The thousands that never tried. European merchant ships could not get insurance and were too slow to evade the blockade, so they stopped calling at Confederate ports. To fight an offensive war, the Confederacy purchased arms in Britain and converted British-built ships into commerce raiders . The smuggling of 600,000 arms enabled the Confederacy to fight on for two more years, and the commerce raiders targeted U.S. Merchant Marine ships in

8415-430: The war created jobs for arms makers, ironworkers, and ships to transport weapons. Lincoln's administration initially struggled to appeal to European public opinion. At first, diplomats explained that the U.S. was not committed to ending slavery and emphasized legal arguments about the unconstitutionality of secession. Confederate representatives, however, focused on their struggle for liberty, commitment to free trade, and

8514-478: The war due to multiple factors: severe food shortages, failing railroads, loss of control over key rivers, foraging by Northern armies, and the seizure of animals and crops by Confederate forces. Historians agree the blockade was a major factor in ruining the Confederate economy; however, Wise argues blockade runners provided enough of a lifeline to allow Lee to continue fighting for additional months, thanks to supplies like 400,000 rifles, lead, blankets, and boots that

8613-603: The war. In December 1860, the Crittenden Compromise was proposed to re-establish the Missouri Compromise line, by constitutionally banning slavery in territories to the north of it, while permitting it to the south. The Compromise would likely have prevented secession, but Lincoln and the Republicans rejected it. Lincoln stated that any compromise that would extend slavery would bring down

8712-436: The winter of 1860–1861. Nationalists in the North and "Unionists" in the South refused to accept the declarations of secession. No foreign government ever recognized the Confederacy. The U.S. government, under President James Buchanan , refused to relinquish its forts that were in territory claimed by the Confederacy. According to Lincoln, the American people had shown they had been successful in establishing and administering

8811-803: The world to provide professional education and networking opportunities. Most hold monthly meetings to exchange ideas about communications, intelligence, cybersecurity and information systems technologies. Nearly one-half of AFCEA's chapters conduct symposia and seminars in addition to other chapter activities. Individual chapters provide college scholarships, fund classroom equipment and mentor students in science fairs and technology clubs. AFCEA conferences offer problem-solving opportunities to C4ISR, intelligence, cybersecurity, homeland security and information technology professionals through exhibits, technical panels and speakers. Events include: American Civil War The American Civil War (April 12, 1861 – May 26, 1865; also known by other names )

8910-478: The world" within a few years. Some European observers at the time dismissed them as amateur and unprofessional, but historian John Keegan concluded that each outmatched the French, Prussian, and Russian armies, and without the Atlantic, could have threatened any of them with defeat. Unionism was strong in certain areas within the Confederacy. As many as 100,000 men living in states under Confederate control served in

9009-488: Was a civil war in the United States between the Union ("the North") and the Confederacy ("the South"), which was formed in 1861 by states that had seceded from the Union. The central conflict leading to war was a dispute over whether slavery should be permitted to expand into the western territories, leading to more slave states , or be prohibited from doing so, which many believed would place slavery on

9108-408: Was high because many soldiers were more concerned about the fate of their local area than the Southern cause. In the North, " bounty jumpers " enlisted to collect the generous bonus, deserted, then re-enlisted under a different name for a second bonus; 141 were caught and executed. From a tiny frontier force in 1860, the Union and Confederate armies grew into the "largest and most efficient armies in

9207-405: Was made of bullion lost from mints. He stated that it would be US policy "to collect the duties and imposts"; "there will be no invasion, no using of force against or among the people anywhere" that would justify an armed revolution. His speech closed with a plea for restoration of the bonds of union, famously calling on "the mystic chords of memory" binding the two regions. The Davis government of

9306-566: Was marked by intense and frequent battles. Over four years, 237 named battles were fought, along with many smaller actions, often characterized by their bitter intensity and high casualties. Historian John Keegan described it as "one of the most ferocious wars ever fought," where, in many cases, the only target was the enemy's soldiers. As the Confederate states organized, the U.S. Army numbered 16,000, while Northern governors began mobilizing their militias. The Confederate Congress authorized up to 100,000 troops in February. By May, Jefferson Davis

9405-512: Was not successful, and with the ironclad CSS  Virginia , rebuilt from the sunken Union ship Merrimack . On March 8, 1862, Virginia inflicted significant damage on the Union's wooden fleet, but the next day, the first Union ironclad, USS  Monitor , arrived to challenge it in the Chesapeake Bay . The resulting three-hour Battle of Hampton Roads was a draw, proving ironclads were effective warships. The Confederacy scuttled

9504-460: Was pushing for another 100,000 soldiers for one year or the duration, and the U.S. Congress responded in kind. In the first year of the war, both sides had more volunteers than they could effectively train and equip. After the initial enthusiasm faded, relying on young men who came of age each year was not enough. Both sides enacted draft laws (conscription) to encourage or force volunteering, though relatively few were drafted. The Confederacy passed

9603-769: Was sworn in as president. In his inaugural address , he argued that the Constitution was a more perfect union than the earlier Articles of Confederation and Perpetual Union , was a binding contract, and called secession "legally void". He did not intend to invade Southern states, nor to end slavery where it existed, but he said he would use force to maintain possession of federal property, including forts, arsenals, mints, and customhouses that had been seized. The government would not try to recover post offices, and if resisted, mail delivery would end at state lines. Where conditions did not allow peaceful enforcement of federal law, US marshals and judges would be withdrawn. No mention

9702-439: Was the principal cause of the secession, a view disproven by historical evidence, notably some of the seceding states' own secession documents . After leaving the Union, Mississippi issued a declaration stating, "Our position is thoroughly identified with the institution of slavery—the greatest material interest of the world." The principal political battle leading to Southern secession was over whether slavery would expand into

9801-525: Was too late. " King Cotton " was dead, as the South could export less than 10% of its cotton. The blockade shut down the ten Confederate seaports with railheads that moved almost all the cotton. By June 1861, warships were stationed off the principal Southern ports, and a year later nearly 300 ships were in service. The Confederates began the war short on military supplies, which the agrarian South could not produce. Northern arms manufacturers were restricted by an embargo, ending existing and future contracts with
