What year did James Pinckney Henderson become the Governor of Texas?

James Pinckney Henderson became the Governor of Texas in 1846. This year is significant because it was shortly after Texas became a state in the United States, following its admission into the Union in December 1845. Henderson's tenure as governor is important in the context of the early years of Texas statehood, as he played a critical role in guiding the state through its initial challenges. His governance coincided with a period of significant change and development in Texas following the end of the Texas Republic era. The other years listed do not correspond with his time in office as governor, making 1846 the correct answer.
