Rome began as a small city-state in Italy. 
Growth happened through many different battles. Rome first fought neighbors like the Sabines and the Etruscans. They also fought the Veientani in the battle of the Cremera. In 390 BC, a group of Gauls invaded from the north. These Gauls were led by a leader named Brennus. They defeated a Roman army of 15,000 soldiers at the battle of the Allia. The Gauls even entered and sacked the city of Rome. This was a very hard time for the Romans.
After the Gauls left, Rome began to expand again. They fought the Samnites, who lived in the Apennine hills. The Samnites were a strong and wealthy group of people. The First Samnite War happened between 343 and 341 BC. Rome also had to fight a war against its own Latin allies. This was called the Latin War. By the end of these struggles, Rome was the strongest state in central Italy. 
Rome continued to win more territory through famous conflicts. They fought the Pyrrhic War from 280 to 275 BC. During this war, a Greek king named Pyrrhus helped the city of Tarentum. Rome also fought the Punic Wars against Carthage. These wars took Roman forces outside of the Italian peninsula. By 241 BC, Rome controlled the island of Sicily. They also gained control of Sardinia and Corsica. 
Finally, Rome completed its control of the whole Italian region. A leader named Augustus took over the Alpine valleys. He did this between 16 BC and 7 BC. He also conquered the lands of the Veneti and the Ligures. Around 7 AD, Augustus divided Italy into 11 different regions. This growth gave Rome a huge number of soldiers. This manpower helped Rome eventually rule much of the Mediterranean world.
The expansion of Rome in Italy was a long series of conflicts. It transformed Rome from a small city-state into the ruler of the entire Italian region. This process lasted from roughly 500 BC until the time of Augustus. Rome grew by conquering various tribes and cities through organized warfare. This growth provided Rome with a massive pool of manpower. This large population of soldiers eventually allowed Rome to interfere in the entire Mediterranean world.
Before the Republic, Rome was ruled by kings. Some of these kings were Etruscans, a powerful people living nearby. Roman tradition says the first kings fought the Sabines and the Latins. Under Etruscan kings like Tarquinius Priscus, Rome expanded toward the northwest. They fought the Veientani, who lived northeast of the Tiber River. In 509 BC, the Romans overthrew their last Etruscan monarch. This event marked the birth of the Roman Republic. At this time, Rome only controlled land within 15 miles of the city. 
As a Republic, Rome faced many immediate neighbors. These included Latin cities and Sabine tribes from the Apennine hills. Rome fought many battles to secure its position. They defeated the Lavinii and the Tusculi at the Battle of Lake Regillus in 496 BC. They also fought the Aequi and the Volsci in several battles. By defeating the Veientani in the wars for Veii, Rome secured its local area. However, Rome was still a minor power in the wider Italian Peninsula. 
In 390 BC, Rome suffered a major setback from the north. Gallic tribes, specifically the Senones, invaded the Italian peninsula. The Romans attempted to help the people of Clusium, but they became the target instead. At the Battle of the Allia, a Gallic leader named Brennus defeated a Roman army of 15,000 soldiers. The Gauls entered and sacked the city of Rome. This humiliating defeat left a deep mark on the Roman conscience. It served as a reminder of the dangers posed by the Celtic peoples.
After the Gallic invasion, Rome resumed its expansion into central Italy. They encountered the Samnites, a wealthy and warlike tribal coalition from the Apennine region. The First Samnite War occurred between 343 and 341 BC. During this time, Rome also faced the Latin War. This was a conflict with their own Latin allies. By the end of these wars, Rome had become the most powerful state in central Italy. They began to look toward the north and the south for more territory. 
The struggle for dominance continued through the Pyrrhic War from 280 to 275 BC. During this conflict, the city of Tarentum sought help from King Pyrrhus of Epirus. Pyrrhus was a Greek king who campaigned in northern Italy. Rome also fought the Punic Wars against Carthage. These wars took Roman forces outside of the Italian peninsula for the first time. By 241 BC, Rome controlled Sicily. By 238 BC, they had also gained Sardinia and Corsica. 
Rome eventually moved to control the northern territories. They subdued the Celtic lands of Cisalpine Gaul between 222 and 200 BC. They also conquered the Veneti to the east and the Ligures to the west. This expansion reached the foothills of the Alps. Finally, the leader Augustus conquered the Alpine valleys between 16 BC and 7 BC. This completed the conquest of the entire Italian geographical region. Around 7 AD, Augustus divided Italy into 11 distinct regions.
Rome incorporated these new lands using several different methods. They used land confiscations to take territory. They also established colonies in new areas. Some people were granted full or partial Roman citizenship. Others entered into military alliances where they remained nominally independent. These various methods helped integrate different cultures into the Roman state. The expansion changed the map of Italy and the future of the Mediterranean.
