3. Changes in Capital:
- Shift from Memphis to Thebes: During the Old Kingdom, Memphis was the prominent capital. Thebes gained importance during the Middle Kingdom, becoming a significant political and cultural center.
4. Cultural and Religious Developments:
- Emphasis on Personal Piety: The focus shifted from grand mortuary complexes to more modest tombs with an emphasis on personal piety and the relationship with the divine.
- Cult of Osiris: The god Osiris became increasingly important, representing afterlife and resurrection, and burial practices centered around this cult.
- The Book of the Dead: The Middle Kingdom saw the development and compilation of the Book of the Dead, a collection of funerary texts and spells for the afterlife.
5. Literature and Art:
- Middle Kingdom Renaissance: The Middle Kingdom experienced a cultural revival with notable advancements in literature and art, including the emergence of Middle Egyptian literature.
- Literary Works: The Tale of Sinuhe and The Instructions of Amenemope are notable literary works from this period.

6. Foreign Relations:
