This study of a northern Spanish community shows how the residents of Santa Mar a del Monte have acted together at critical times to ensure the survival of their traditional forms of social organization. The survival of these forms has allowed the villagers, in turn, to weather demographic, political, and economic crises over the centuries. Originally published in 1991. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
