Historical Irony
I've been reading Texian Illiad (not an affiliate link) by Stephen L. Hardin. It's a history of the Texas fight against Mexico for independence. Overall it's a pretty good read. Alas there is some fine irony mentioned in the book.
Mexico was having trouble getting people to colonize the northern Texas area so they started making deals. Basically you could nab some free (in price and tax) land by settling in specific regions. American citizens of course took Mexico up on this offer which was the basic idea. Well apparently a lot of Americans just started showing up and settling in without getting the proper paperwork from the Mexican government. One of the biggest concerns for the Mexican government was the illegal immigrants from America.
Oh how I love irony!
