<a href=http://en.wikipedia.org/wiki/Senusret_I>Senusret I</a> was one of the most powerful pharaohs of the greatest dynasty of the Middle Kingdom period of ancient Egypt. He expanded Egypt's borders through a series of military campaigns and built many temples and shrines throughout the Kingdom. His most famous works include a pair of red granite obelisks erected to celebrate his 30 year Jubilee (one of which remains as the oldest standing obelisk in Egypt), as well as the White Chapel, a temple which has recently been reconstructed at its original location in Karnak.
