Who was the first governor of New Mexico after it became a state?

William C. McDonald holds the distinction of being the first governor of New Mexico after it achieved statehood on January 6, 1912. His tenure as governor lasted from 1912 to 1917, and he was a member of the Democratic Party. McDonald’s administration was significant in establishing a framework for the newly admitted state, addressing educational reforms, and various infrastructure projects as New Mexico transitioned from a territory to a state.

The other individuals listed, while important figures in New Mexico's political history, served as governors during a later time. Bruce King, Bill Richardson, and Susana Martinez were all governors in the latter half of the 20th century and into the 21st century, each contributing to state governance and policy in their respective eras but not as the first to hold the office post-statehood.
