The State of Israel was proclaimed on 14 May 1948, the culmination of nearly 2,000 years of hopes by Jewish people that they would one day return to the land from which the Romans expelled them.
Polk accomplished this through the annexation of Texas in 1845, the negotiation of the Oregon Treaty with Great Britain in 1846, and the conclusion of the Mexican-American War in 1848, which ended with the signing and ratification of the Treaty of Guadalupe-Hidalgo in 1848. The Battle of Veracruz. These events brought within the control of the United States the future states of Texas, California, Nevada, New Mexico, Arizona, Utah, Washington, and Oregon, as well as portions of what would later become Oklahoma, Colorado, Kansas, Wyoming, and Montana.
With the strong approval of most Texans, Polk signed the legislation making Texas an American state on December 29, 1845. Ominously, the Mexican minister had meanwhile warned the U.S. that his nation would consider annexation an act of war and demanded his passport in preparation for departure.
