When Nero tired of his own mother, Agrippiana The Younger, he decided to have her killed. He sent her out to sea alone in a ship that was rotted and falling apart. The ship broke in half and sank right in the harbor, but the strong Agrippiana held on, and was rescued by a fisherman. Angered that his first plan failed, he hired two naval officers to find her, and slit her throught in her sleep.
Nero's murder of his mother was only the first such incident. He also seemed to tire of his wives. He first married an rigid, uptight woman named Octavia. That didn't last. He got tired of her, and had her killed. Being bored with being single, he had another woman's husband killed, just to mary her. He got bored with her too, and had her killed, too. Finally, his third and final wife, Popeala, was as hyper as him, and at a party, he kicked her to death in a drunken riot.
Besides thinking he was a great husband, Nero also thought he was the best poet in excistence. At one time, he supposedly burned down half of Rome, killing thousands, just for inspiration for a poem about the burning of Troy. He blamed it on Christians, and they were put through the worst religous persecution ever that any religion has ever faced. Hundreds to thousands of Christians were flung into the dungeon, where they were tortured, then thrown into the arena to be slaughtered by the lions, or killed in duals. Romans came from all over the Empire, just to see these bloody and gruesome event.
Nero always prided himself on the support of his army. But, in 64 AD, his army turned against him. They stormed his castle of gold, and the few guards he had left on his side were mercilessly slaughtered. The army searched his castle for a while, before one of his guards found him, lying in his chambers, knife in hand, and a gash in his throught. Nero had killed himself.
