Answer:
The above concerns affect Texas during the period of Annexation of Texas
Explanation:
Before the Annexation of Texas by the United States on 29th December 1845, the United States Congress feared a possible war with Mexico, this is because the Texas territory was initially part of the Mexico country before it declared independence.
Also, Abolitionists feared the expansion of slavery, this is because the Texas territory was a slave territory at the time, and the United States abolitionist believed that annexation of Texas would increase the Slave States
Northern states feared the addition of another slave state would lead to a Civil War, this is because the Northern states are free, and with the inclusion of Texas, which is slave territory, there would be more agitation and counter agitation of the issue of slave and free state which may lead to civil war eventually.
