The pharaohs of the new kingdom, which dissolved Egypt, all had one claim that they wanted to preserve for centuries: they had expelled Egypt's foreign invaders from their land and unified a divided land. The pharaohs believed that they could not achieve this without the help of the god Amun-Re, this was their ideology (the relationship between the god Amun and the pharaoh). The pharaohs of the 18th Dynasty preserved this statement in their building programs. Once a new pharaoh came to power, they began a program that defined all construction activities during the pharaoh's reign. Construction projects were carried out mainly for political and religious reasons (with the exception of housing). Political and religious reasons for building programs include: ideology of kingship, dedication to the cult of Amun, honoring the cults of Egyptian gods, funerary monuments and self-promotion of the pharaoh, and border protection. The construction programs remind current pharaohs and the Egyptian people of the triumphs and victories of past pharaohs. The pharaohs used building programs to show loyalty and respect to the gods and goddess of Egypt. Some 18th Dynasty pharaohs who contributed greatly to the building programs were Hatshepsut, Thutmose III, and Thutmose IV. Hatshepsut During Hatshepsut's reign she built a mortuary temple at Deir el-Bahri, at the head of the valley below the mountain peak. The temple was built into the rock face so that the building seemed to have grown out of the rock. After Hatshepsut's death the monument was purposely deconstructed by Thutmosis III and Akhenaten as a direct attack on Hatshepsut. Today the monument is in a semi-destroyed state due to atmospheric agents. The temple has features such as the entrance pylon, the first... in the center of the card... performing rituals before the god Amun. This building program was significant for the development of the cult of Amun through additions to the temple of Amun at Karnak. The temple was not the only contribution that Thutmose IV made to the cult of Amun; he also built a sanctuary for Amun's boat and added a golden portico in front of the 4th pylon. Other construction projects of Thutmose IV include the completion of the pre-existing eastern obelisk dedicated to the cult of Amun, built at the Karnak temple, by his grandfather Thutmose III. The unique obelisk is the tallest obelisk ever built in Egypt, reaching 32 meters in height. Thutmose used building programs to expand the cult of Amun through additions to the temple of Amun at Karnak. The king believed that by recording his association with the god Amun on monuments, he was depicted as a god, rightfully ruling the lands of Egypt.
