James Wilson (Indiana politician)

Wilson served in the United States military during the Mexican–American War from June 17, 1846, to June 16, 1847.

After he turned to Crawfordsville in 1847, Wilson worked in the law office of Tilghman Howard (later the namesake of one of his sons), and he was admitted to the bar in 1848. Wilson became actively involved in politics in the mid-1850s, and he was a member of the newly formed Republican Party. In 1856, Wilson decided to run for the seat of 8th District Indiana Representative. During the election, Wilson defeated Daniel Wolsey Voorhees, and Wilson officially became a member of Congress on March 4, 1857. During the congressional election of 1858, Wilson was reelected. Wilson's time in Congress came to an end on March 3, 1861. He had served in the Thirty-Fifth and Thirty-Sixth Congresses of the United States of America.

During the American Civil War, Wilson was appointed captain of Volunteers on November 26, 1862. He was honorably discharged from the military on December 6, 1865, with the rank of brevet lieutenant colonel. At the end of the war, Wilson returned to his law practice in Crawfordsville.

In 1866, President Andrew Johnson appointed Wilson to the position of Minister Resident to Venezuela. He served in this capacity from 1866 until his death in Caracas, Venezuela, on August 8, 1867. Wilson is buried in Oak Hill Cemetery, Crawfordsville, Indiana.
