By 1853, Democrats splintered along sectional lines over slavery, while Illinois Senator Stephen A. Douglas worked on a bill to organize what territory-the last of the Louisiana Purchase lands-which extended from northern Texas to the Canadian Border

The territory (the last of the Louisiana Purchase lands) that Senator Stephen A. Douglas worked on a bill for, included the 1853 Nebraska Territory which was huge and extended from the northern end of Texas to the Canadian Border: the whole territory can be compared to the area encompassing all of the present-day Colorado, Montana, Nebraska, North Dakota, South Dakota, and Wyoming.

Explanation:

In 1853, the Democrats were fragmented and in disagreement over slavery but still had conviction to keep on moving forward together; this resulted in voters electing them to office in 1852 after the party's bitter internal fights over the Compromise of 1850. Courageous and highly motivated Illinois senator, Stephen A. Douglas, then amended a bill that was drafted in the ending part of 1853, in order to assist in organizing the Nebraska Territory-the last of the Louisiana Purchase lands-which was huge and extended from the northern end of Texas to the Canadian Border: the whole territory can be compared to the area encompassing all of the present-day Colorado, Montana, Nebraska, North Dakota, South Dakota, and Wyoming.
