Answer:
In December of 1845, Texas became the 28th state of the United States of America. It was a change welcomed by many. As early as 1836, Texan voters had chosen overwhelmingly to support annexation. But opposition in the U.S. was strong, and the annexation of Texas came only after years of heavy debate.
Step-by-step explanation:
Some of that debate came from Texan nationalists. But the main opposition was found in the US. The issue of slavery was central to their concerns – as it was with so many political issues in the US at the time. There had been little question that if Texas joined the U.S., it would join as a slave state. Slavery was widespread in the Republic of Texas. Although no formal census was taken in Texas until 1850, it’s estimated that in 1845 the new state had a population of about 125,000 people. Some 30,000 lived as slaves. Abolitionists in the U.S. worried that adding another slave-holding state would upset the political balance in Congress and in the country.
