Always with the missing context.

Well this is a fascinating detail which I would expect to have a broader public awareness than it has.  I have probably read three books, maybe six, on the Texas War for Independence and the Alamo, and I was not aware of this context.

From What Nobody Tells You About the Alamo and the Texas Revolution of the 1830s by Erik at No Passaran.  There was a recent dust-up when the Texas State Historical Association’s chief historian, Walter Buenger, declared that the battle of the Alamo as an insignificant battle then and a monument to white supremacy now.

Racist idiocy of the first order.  

Erik points out the missing context.  Mexico was made up of a federation of twenty states, and in 1835, General Antonio López de Santa Anna staged a coup and overturned the Mexican Constitution of 1824 which among other things outlawed slavery.  

Eleven of the twenty states rebelled against the de Santa Anna coup (Wikipedia identifies fifteen states who rebelled against Santa Anna's coup).  Some sought to restore the 1824 Constitution and others sought independence from the new Junta. In fact, de Santa Anna's first battle was against the self-declared Republic of Zacatecas.  Ultimately three of Mexico's states declared independence, including Texas.  The Republic of the Yucatan lasted seven years.

Contra Woke Buenger, Texas was only one of some fifteen (of a total of twenty) Mexican states which rebelled against Santa Anna's coup, and one of the three which declared independence against Santa Anna.  Racism and white supremacy had nothing to do with these rebellions and independence movements - they were all efforts to support a Constitutional nation against the threats and violence of a dictator.
