Topeka was a bastion for the free-state movement during the problems in Kansas Territory between abolitionist and proslavery settlers (the latter of whom controlled the legal government based out of Lecompton). After southern forces barricaded Topeka in 1856, Topeka's leaders took actions to defend the free-state town from invasion. A militia was organized and stone fortifications were built on Quincy Street. The fortifications seemed to consist of low-lying earthwork levies strengthened by the presence of at least one cannon. The militia manned the fortifications until at least September 1856, when the siege around the town was lifted.
