How long did it take for New Mexico to achieve statehood after becoming a territory?

New Mexico was designated as a U.S. territory in 1850 following the Treaty of Guadalupe Hidalgo, which ended the Mexican-American War. It wasn't until January 6, 1912, that New Mexico achieved statehood. By calculating the time from its establishment as a territory to statehood, it took a span of 62 years. Therefore, choosing the answer of 60 years is the closest to the actual timeframe.

This lengthy process was influenced by various factors, including the region’s demographics, economic development, and political considerations, as well as debates over the conditions for statehood and the significance of local governance versus federal control. The other options do not accurately reflect the historical timeline for New Mexico's journey from territory to state.
