Texas throughout its history has hosted several Utopian and Socialist Communes, the focus of this idea being, La Reunion which in OTL eventually joinned to form Dallas, Texas. La Reunion as well as several other Socialist Communes were established primarily in the wake of the failed 1848 Revolutions in Europe which saw a surge of immigration to the Americas of these Revolutionaries, Utopians, Anarchists and so forth from Dallas to Austin, Texas and immigrant communities in Central and North Texas. Many of these Utopians came ins everal different degrees but I am looking for La Reunion's founder Victor Considerant's views (Proportional Representation, Direct Democracy, Private Property Allowed for example) to come out on top.
The problem with La Reunion for example is inpart due to that its population were urbanites not farmers and that the land they settled was very poor for farming. To make any of these communes work therefore the Utopian Socialist Ideology would have to offer more to the Peasents and Agriculturalists (alot like the Russian 'Land and Liberty' revolutionaries) to get them either from Europe or America to either pick better land to settle on or survive better to what they had. Given the amount of land going up for sale in Texas this would be an attraction and I am sure they could fit in 'all the free land you want'. Once able to sustain themselves their Urbanite Craft Skills such as Weaving Clockmaking, etc should come in handy when trading with local American settlers that may not be as skilled to draw in trade and to spread the Socialist Ideology.
Eventually this would lead up to the American Civil War which would see East Texas focused around Houson seceding from West Texas to join the Confederacy after the spread of the Utopian Socialist Ideology improves the support of Anti-Slavery and Pro-Unionism.
