The Romans made a new town and wanted to expand it but it was full of all men. So they thought to invite the Sabines so they could bring their woman and steal them to increase the population.
Althought the Romans knew what was happening, the Sabines didn't. So they proceeded to come to the "party."
As the Sabines were having fun and partying, the Roman men planned their attack and started taking the women.
The women started slowly falling in love with the Roman men. The Sabines were planning a war against the Romans but they were taking so long, that some of the women already had children with the Romans.
