The only successful European empresarios in mid-nineteenth-century Mexican Texas - men authorized to bring immigrants to settle the vast spaces of Mexico's northern territories - were Irish. On their land grants, Irish settlers founded Refugio and San Patricio and went on to take active roles in the economic and political development of Texas. It required a hardy spirit and strong ambition to weather the perils that accompanied these opportunities - the long journey, shipwrecks, hostile Indians, injury and disease - and Irish pioneers proved fit for the task. They were not seeking relief from famine or English oppression in their own country. These were vigorous, strong-willed people who possessed the monetary means to remove themselves from their insular surroundings. What they were seeking, and what they obtained, was land.
