The historical links between U.S. President Abraham Lincoln and Mexican President Benito Juárez have been long studied by historians. The shifting of the course of the Rio Grande that began the Chamizal conflict began while these two Presidents were in office, and both were locked in battles to save their respective republics (The Civil War for Lincoln, The War against France for Juárez). Juárez was born on March 21, 1806, in the village San Pablo Guelatao in the State of Oaxaca. He was of Zapotec Indian heritage. After his parents and grandparents died he lived first with his uncle and herded sheep. Eventually he was cared for by a Franciscan lay-brother who began to educate him. Juárez studied theology and law. In 1847, he was governor of Oaxaca, and in 1858, President of Mexico. As a defender of democracy he stated: "Among individuals, as among nations, respect for the rights of others is peace." In 1862, Napoleon Ill invaded Mexico and later made Maximilian of Austria, emperor of Mexico. French troops forced Juárez to flee from the nation's capital from one town to another. In 1864, he arrived in Chihuahua City. In August 1865, he retreated to El Paso del Norte which, for nine months (1865-66), was Mexico's capital. He declined offers of asylum and invitations from Fort Bliss Army officers and El Paso residents. He vowed never to leave Mexican soil as long as it was occupied by foreign invaders. During his time in El Paso Del Norte, President Juárez helped build a new irrigation system to replace the canals that had been destroyed by floods. Juárez also met with the Chamizal residents who requested that their lands be returned which recent river floods had been had placed on the north bank, which were subsequently claimed by Norte Americanos. That boundary dispute, which was revolved a century later, resulted in the Chamizal Convention and the creation of the two commemorative parks - Parque Chamizal and the Chamizal National Memorial. Soon after Juárez left Paso del Norte, in 1866, he successfully re-united his nation. On September 16, 1888, the people of El Paso del Norte proudly re- named their town Ciudad Juárez in honor of their special friend and guest, the Citizen President of Mexico.
