Who was Henry Clay, was he robbed of the presidency in those conventions?

Clay ran for president five times, 1824, 1832, 1840, 1844, and 1848. In two of these elections, 1832 and 1844, he was his party’s nominee. In 1824, he was one of four candidates on the election day ballots where all of them were from the same party. He was a general election candidate three times. He lost his party’s nomination two times, both to two generals who were far less able politicians than him, William Henry Harrison and Zachary Taylor. Clay was nearly the nominee in both of these elections. He created the National Republican Party and the Whig Party. When the National Republican Party fell, most of its members went to the Whig Party, and when the Whig and Free Soil Party collapsed some former members made the Republican Party, mostly former Whigs, including Abraham Lincoln, who joined the new party.
