Founded by Romulus (the first King of Rome) and Remus on April 21st 753 B.C., the city was in fact built by the Etruscans. The expulsion of the last King of Rome coincided with the decline of the Etruscans. Carthage finally fell for good in 146 B.C. and was almost completely razed to the ground by the Roman troops under the command of Publius Cornelius Scipio Aemilianus. The Republic began to topple in I B.C. leading to the revolt of the slaves led by Spartacus. The dictatorship of the Caesars lasted from 46 to 44 B.C., only to be followed by the rise of Octavius (44-30 B.C.). The "second" Triumvirate of 27 B.C. and the rise to power of Settimius Severus (193-211 A.D.) led to a reform of the institution of the principality. Christianity progressively became the only religion. By 5 A.D. the Empires of the East and the West were divided, with the result that the Pope became one of the most important religious figures in the entire Byzantine Empire and extremely powerful. The Lombards invaded Rome between 565-578. Rome was the capital city during the Pontificial State and became the centre of Christianity, at least where Latin rituals were used, in the world. Although the Pope’s power was not actually enough to allow him to govern, it grew steadily and any Republican experiences became gradually less significant until they died out completely. Rome was also an extremely important centre of culture during the Renaissance. The Papal rule was interrupted by the short-lived Roman Republic (1798), in fact the Republic of Rome as such dates from 1849. The Franco-Prussian war started in 1870 with the Italian army entering Rome (the capture of Rome) on September 20th. Rome and Lazium were annexed to the Kingdom of Italy. Rome underwent severe bombing during the Second World War. As it was considered an "open city", Rome was spared the complete destruction that took place in Berlin and Warsaw, the first capital in the Axis countries to fall into the hands of the Allies on June 4th 1944. Rome hosted the 1960 Olympic Games. Many monuments were restored in Rome for the 2000 Jubilee Year.
