A) that states had the constitutional right to secede from the United States
Explanation:
James Buchanan was the 15th president of USA. It was during his presidency that seven southern states seceded from the Union and brought the nation on the brink of civil war.
He was from Pennsylvania and began his career in Pennsylvania state's legislature. He later served in both the houses of the U.S congress.
Buchanan was a democrat and he morally opposed slavery while believing that it was supported by the US constitution.. He got elected to the White House in 1856.
He tried to maintain peace between the anti and pro slavery factions in the government.<u><em> In 1856 general election Buchanan supported the idea that slavery was an issue to be decide by the individual territories and states while his challenger John Fremont asserted that the federal government should bad slavery in all the territories.</em></u>
He did not seek reelection after his first term as president but he proposed that sates did not have the right to secede and he had no constitutional power to stop them. The slavery crisis was left for the Lincoln administration to resolve.

The Crusades were a series of military campaigns organised by Christian powers in order to retake Jerusalem and the Holy Land back from Muslim control. There would be eight officially sanctioned crusades between 1095 CE and 1270 CE and many more unofficial ones. Each campaign met with varying successes and failures but, ultimately, the wider objective of keeping Jerusalem and the Holy Land in Christian hands failed. Nevertheless, the appeal of the crusading ideal continued right up to the 16th century CE.
