The work of the children was a common custom among peasant and artisan families. In the first decades of the industrial revolution, a large number of boys and girls worked in factories and coal mines. The industrial revolution produced important changes in the lives of millions of people. Many started working in factories and many of them were children. In the first English factories, these children were under the age of seven, forced to work between twelve and fifteen hours every day of the week. They did not eat properly, they were in an environment full of danger and dirt, they could not go to school or play because they spent long hours working.
<em>In the Middle Ages the title of knight was granted to the bravest warriors, these were given land outside the palace of the king, to protect him from enemies.</em>
