Who was the first governor of Oklahoma?

George W. Steele was the first governor of Oklahoma, taking office when the state was admitted to the Union on November 16, 1907. His administration focused on the establishment of a functioning state government, creating laws, and setting up various state institutions. Steele was a prominent figure during a transformative time for Oklahoma, which had just transitioned from Indian Territory and was organizing its political and administrative frameworks. His role as the inaugural governor played a significant part in shaping the state's early policies and identity, marking the beginning of Oklahoma's governance as a state rather than as a territory. This historical significance distinguishes him as the correct answer to the question.
