Livy provides a short, detailed story of the personal and political life of Servius Tullius, including how Tanaquil helped Servius Tullius to the throne and his relationship with the sons of King Ancus Marcius (Martius) and the Tarquins.This timeline provides the sequence and dates of the 7 kings of Rome. There is also a brief description of each of the kings.Servius Tullius is credited with making constitutional reforms and performing a census, increasing the number of tribes, and adding many people to the category of those eligible to participate in the voting assemblies.The Servian reform of the citizen body affected the military as well, since Servius added a number of new bodies to the count. Servius divided the men into centuries, which were military units. The familiar centurion figure in the Roman legions is associated with these centuries. He divided the centuries into older and younger divisions so that there would be about half the number of men to stay and guard the home front while the other half went off to fight the almost incessant Roman wars.We don&#39;t know whether Servius Tullius created more than the four urban tribes, but his re-alignment of the citizens into geographic rather than family-based units led to the creation of 35 tribes. The tribes voted in the tribal assembly. After the number 35 was set as the final figure, new citizens were added to those groups, and the geographic character of the affiliation was diminished. Some tribes became relatively more crowded which meant that individuals&#39; votes counted for proportionately less since only the vote of the group counted.Servius Tullius is credited with enlarging the city of Rome, and building the Servian Wall connecting the Palatine, Quirinal, Coelian, and Aventine hills, and the Janiculum. He is credited with building the Temple of Diana on the Aventine (Diana Aventinensis) to serve as a center for the cult of Diana for the Latin League. Sacrifices for the Secular Games were made to Diana Aventinensis. Archaeologists believe the walls and temple were built somewhat later. Servius Tullius also associated with the goddess Fortuna to whom he built several shrines, including the one on the Forum Boarium.<p>See: Chapter &#34;Enlargement of the City Of Rome -- Servian Wall,&#34; from .</p>Servius put in place the Comitia Centuriata, the voting assembly based on the the division of the people of Rome into centuries based on their economic class.
