Eventually the Ottoman Empire sent him to many different cities, including Constantinople, Adrianople, Alexandria, and eventually Akka. He was in different jails this whole time, and the city of Akka had a big wall around it, and it was one big jail. While he was in Baghdad, and after, he wrote many books and letters to answer questions that his friends and followers asked him. At one point he was poisoned, so that he could not write anymore because his hands shook so badly. After that, he had someone write down what he said. When he was even older, his oldest son, `Abdu'l-Bahá arranged to have him move into a house near Mount Carmel, and he stayed there until he finally died in 1892.
