Arizona is the 48th state and last of the contiguous states to be admitted to the Union, achieving statehood on February 14, 1912. Historically part of the territory of Alta California in New Spain, it became part of independent Mexico in 1821. After being defeated in the Mexican–American War, Mexico ceded much of this territory to the United States in 1848. The southernmost portion of the state was acquired in 1853 through the Gadsden Purchase.
One of the original Thirteen Colonies, Maryland is considered to be the birthplace of religious freedom in America, when it was formed by George Calvert in the early 17th century as an intended refuge for persecuted Catholics from England. George Calvert was the first Lord of Baltimore and the first English proprietor of the then-Maryland colonial grant. Maryland was the seventh state to ratify the United States Constitution, and played a pivotal role in the founding of Washington, D.C., which was established on land donated by the state.
