Past
Boudicca was born into the tribe of Iceni, a tribe that didn't want any Romans to be near them because of the history the Celts had with Julius Ceaser attacking Britian. Not making a treaty with the Romans, thinking that it would ruin their reputation, but soon the the Celts gave in and made a treaty with with that Romans like what the other tribes had done. Finally the Iceni decided to have a king, Prasutagus, a few years later Prasutagus married Boudicca as his queen. It was only for a small amount of time before Prasutagus died.
Kingdom
Prasutagus had left half of his kingdom to Boudicca and the other half to Emperor Nero, but Nero decided to take the whole kingdom for himself. Emperor Nero was adopted by Claudius, his great uncle. At a young age he had a passion for music, theater and horse racing. The Romans started to take the Celts property without any permission which made the Celts furious.
Celts
The Celts were a religious tribe. thinking that sometimes for the better good, they would have to sacrafice some of their own people. On certain basis they would have ceremonies with a feast and the nobles there to watch. There would be also ceremonies for funerals where they would bury the dead with jewelry and treasures. It was a time where there were kings and queen with wars and many hardships that we don't have today. It was the past that led to more change.
