Why did president james k. polk support the u. s. acquisition of both texas and the entire oregon territory?

Polk was in favor of acquiring both Texas and Oregon because he was a firm believer in manifest destiny.

Manifest destiny is the belief that it is America's god-given right to take over all of the land from the Atlantic to the Pacific Ocean. This belief that it was inevitable that this land would belong to the US prompted the federal government to acquire lands like Texas and Oregon. We acquired Texas after they became free from Mexican rule and we would go on to control a significant amount of the Oregon territory after striking a deal with Great Britain.

- "the past is made of multitudinous items ranging from anything that can be collected, recollected or assessed to originate in the past. as such, the past is a gallimaufry of particulars that may not have been related in any way. however, the human mind seeks organization to understand concepts and other things. the human mind therefore seeks relationships in explaining and studying the past. history being a humanity, dictates that historians have to serve this human trait by bringing structure to details of the past. historians do this by creating interpretive frameworks that capture as many details as possible."
