_Government._--The present municipal constitution of the city dates from 1867 and presents some points of difference from the ordinary Prussian system. Bismarck was desirous of giving the city, in view of its former freedom, a more liberal constitution than is usual in ordinary cases. Formerly fifty-four representatives were elected, but provision was made (in the constitution) for increasing the number, and they at present number sixty-four, elected for six years. Every two years a third of the number retire, but they are eligible for re-election. These sixty-four representatives elect twenty town-councillors, ten of whom receive a salary and ten do not. The chief burgomaster (Oberbuergermeister) is nominated by the emperor for twelve years, and the second burgomaster must receive the emperor's approval. Since 1885 the city has been supplied with water of excellent quality from the Stadtwald, Goldstein and Hinkelstein, and the favourable sanitary condition of the town is seen in the low death rate. _Population._--The population of Frankfort has steadily increased since the beginning of the 19th century; it amounted in 1817 to 41,458; (1840) 55,269; (1864) 77,372; (1871) 59,265; (1875) 103,136; (1890) 179,985; and (1905), including the incorporated suburban districts, 334,951, of whom 175,909 were Protestants, 88,457 Roman Catholics and 21,974 Jews. _History._--Excavations around the cathedral have incontestably proved that Frankfort-on-Main (_Trajectum ad Moenum_) was a settlement in Roman times and was probably founded in the 1st century of the Christian era. It may thus be accounted one of the earliest German--the so-called "Roman"--towns. Numerous places in the valley of the Main are mentioned in chronicles anterior to the time that Frankfort is first noticed. Disregarding popular tradition, which connects the origin of the town with a legend that Charlemagne, when retreating before the Saxons, was safely conducted across the river by a doe, it may be asserted that the first genuine historical notice of the town occurs in 793, when Einhard, Charlemagne's biographer, tells us that he spent the winter in the villa Frankonovurd. Next year there is mention more than once of a royal palace here, and the early importance of the place is indicated by the fact that in this year it was chosen as the seat of the ecclesiastical council by which image-worship was condemned. The name Frankfort is also found in several official documents of Charlemagne's reign; and from the notices that occur in the early chronicles and charters it would appear that the place was the most populous at least of the numerous villages of the Main district. During the Carolingian period it was the seat of no fewer than 16 imperial councils or colloquies. The town was probably at first built on an island in the river. It was originally governed by the royal officer or _actor dominicus_, and down even to the close of the Empire it remained a purely imperial or royal town.
