Hagan (1845), that the Constitution mandated admission of new states on the basis of equality. Historically, most new states formed by Congress have been established from an organized incorporated U.S. territory, created and governed by Congress in accord with its plenary power under Article IV, Section 3, Clause 2 of
1800-471: The 1787 Northwest Ordinance , both of which predate the U.S. Constitution.

2550-465: The Union has been delayed by complicating factors. Among them, Michigan Territory , which petitioned Congress for statehood in 1835, was not admitted to the Union until 1837, because of a boundary dispute with the adjacent state of Ohio. The independent Republic of Texas requested annexation to the United States in 1837, but fears about potential conflict with Mexico delayed the admission of Texas for nine years. Also, statehood for Kansas Territory

American Indian peoples predominant in the area included the Nez Percé in the north and the Northern and Western Shoshone in
2925-465: The areas that are south of the ice sheet. An early presence of French-Canadian trappers is visible in names and toponyms : Nez Percé, Cœur d'Alène, Boisé, Payette .

Idaho, as part of the Oregon Country ,

The forest is administered from Salt Lake City, Utah as part of the Wasatch-Cache National Forest, but there are local ranger district offices in Logan and Ogden .

3375-502: The first people might not have come to North America by land, as previously theorized. On the contrary, they probably came through the water, using a Pacific coastal route. The most parsimonious explanation we think is that people came down the Pacific Coast, and as they encountered the mouth of the Columbia River, they essentially found an off-ramp from this coastal migration and also found their first viable interior route to

The same year Congress created Colorado Territory, a county called Idaho County
SECTION 50
#17327837626483900-410: The new Constitution went into effect Congress admitted Vermont and Kentucky on equal terms with the existing 13 states and thereafter formalized the condition in its acts of admission for subsequent states.

The broad outline for the process was established by the Land Ordinance of 1784 and
4725-401: The top countries of origin for Idaho's immigrants were Mexico, Canada, the Philippines, China and Germany. Idaho's population increased by 17.3% from 2010 to 2020, the second fastest rate of growth of any state that decade.

This influence has a moderating effect in the winter where temperatures are not as low as would otherwise be expected for a northern state with predominantly high elevations.

As a result of this compromise, new breakaway states are permitted to join the Union but only with the proper consents. Shortly after

It is unclear whether the steamship was named before or after Willing's claim was revealed. Regardless, part of Washington Territory, including Idaho County, was used to create Idaho Territory in 1863. Idaho Territory would later change its boundaries to
5400-477: Was held up for several years (1854–1861) because of a series of internal violent conflicts involving anti-slavery and pro-slavery factions.
