was subdivided into ten curić, and each curia into decurić, headed by leaders called curiones and decuriones.
Besides this, out of each tribe was taken a body of one hundred Equites or Knights, called a century, which shows that these divisions, being unnecessary in a town, were at first merely military. But an instinct for greatness seems to have led the little township of Rome to provide itself in advance with a political system suitable for the capital of the world.
Out of this original division an awkward situation soon arose. The tribes of the Albans (Ramnenses) and the Sabines (Tatienses) remained always in the same condition, while that of the foreigners (Luceres) continually grew as more and more foreigners came to live at Rome, so that it soon surpassed the others in strength. Servius remedied this dangerous fault by changing the principle of cleavage, and substituting for the racial division, which he abolished, a new one based on the quarter of the town inhabited by each tribe. Instead of three tribes he created four, each occupying and named after one of the hills of Rome. Thus, while redressing the inequality of the moment, he also provided for the future; and in order that the division might be one of persons as well as localities, he forbade the inhabitants of one quarter to migrate to another, and so prevented the mingling of the races.
He also doubled the three old centuries of Knights and added twelve more, still keeping the old names, and by this simple and prudent method, succeeded in making a distinction between the body of Knights, and the people, without a murmur from the latter.
To the four urban tribes Servius added fifteen others called rural tribes, because they consisted of those who lived in the country, divided into fifteen cantons. Subsequently, fifteen more were created, and the Roman people finally found itself divided into thirtyfive tribes, as it remained down to the end of the Republic.
The distinction between urban and rural tribes had one effect which is worth mention, both because it is without parallel elsewhere, and because to it Rome owed the preservation of her morality and the enlargement of her empire. We should have expected that the urban tribes would soon monopolise power and honours, and lose no time in bringing
