Why did southern senators initially block the organization of the kansas and nebraska territories? they thought the railroad that would be built there would only benefit the north. they did not think the area’s american indians should be moved to oklahoma. they worried that the area’s american indians would be relocated to the south. they were afraid the admission of new free states would tip the balance.

Option D.

Explanation:

Southern senators initially blocked the organization of the Kansas and Nebraska territories as they were afraid the admission of new free states would tip the balance. In the verge of the beginning of the Civil War, the Kansas-Nebraska Act was introduced in 1854 as a last attempt to secure the peace between the north and the south. Southern senators opposed the act because they were concern that it would bring more representation to the Congress. If the act was passed, it meant that the two territories would be free states when entering the Union. In the eyes of the southern senators this meant that the Congress was going to have more members who opposed the southerners' views on slavery.
