When, in 1910, like several of its sister republics, Mexico celebrated the centennial anniversary of its independence, the era of peace and progress inaugurated by Porfirio Diaz seemed likely to last indefinitely, for he was entering upon his eighth term as President. Brilliant as his career had been, however, and greatly as Mexico had prospered under his rigid rule, a sullen discontent had been brewing. The country that had had but one continuous President in twenty-six years was destined to have some fourteen chief magistrates in less than a quarter of that time, and to surpass all its previous records for rapidity in presidential succession, by having one executive who is said to have held office for precisely fifty-six minutes! It has often been asserted that the reason for the downfall of Diaz and the lapse of Mexico into the unhappy conditions of a half century earlier was that he had grown too old to keep a firm grip on the situation. It has also been declared that his insistence upon reelection and upon the elevation of his own personal candidate to the vice presidency, as a successor in case of his retirement, occasioned his overthrow. The truth of the matter is that these circumstances were only incidental to his downfall; the real causes of revolution lay deeprooted in the history of these twenty-six years. The most significant feature of the revolt was its civilian character. A widespread public opinion had been created; a national consciousness had been awakened which was intolerant of abuses and determined upon their removal at any cost; and this public opinion and national consciousness were products of general education, which had brought to the fore a number of intelligent men eager to participate in public affairs and yet barred out because of their unwillingness to support the existing regime.
