What are two legends that describe romes founding? How are the two legends connected

Eventually the two brothers quarreled resulting in the murder of Remus, leaving Romulus as the first King of Rome. The traditional date of Romulus' sole reign and the subsequent founding of the city, April 21, 753 BC, is still celebrated with festivals and parades today.

the legend of the founding of Rome by the twin brothers, Romulus and Remus. Their grandfather was the rightful king of Alba but he had been deposed by his brother. Their mother was supposed to be a virgin priestess of the goddess Vesta, but she got pregnant, some say by Mars, the god of war. Their great-uncle recognised that Romulus and Remus were more than human and attempted to have them killed. The Romans themselves were in no doubt when Rome was founded: 21 April 753 BC. On that day of the year, too, they celebrated the traditional festival of the Parilia, in honour of Pales, the god (or goddess - the Romans were notoriously vague about the gender of some of their deities) of shepherds and sheep. In 1948 traces were found on the Palatine Hill, the central and most easily fortified of the hills of the ultimate city, of the huts of a settlement of shepherd folk dating from about 750 BC. Recent excavations uncovered the remains of a ritual boundary wall of about the same period.
