The Normans brought peasants (poor farmers) from England and Wales to Ireland. They sold them to lords. The peasants lived in villages. A village and the land around it was called a Manor. The Manor belonged to the lord. Some lords had castles on their Manor. But many lords could not afford to build a castle. They lived in a house. It is called the Manor-House. Irish towns began in the middle ages. The Vikings started some towns and the Normans started others.
