The Book of Esther was likely written in the context of the Jewish diaspora, specifically during or after the time of the Persian Empire in the 5th century BCE. During this period, many Jews were living outside of their homeland, having been exiled during the Babylonian captivity. After Babylon fell to the Persians in 539 BCE, Jews were allowed to return to Judea, but many remained scattered throughout the vast Persian Empire, including in cities like Susa, where the story of Esther takes place.

Key Historical and Cultural Contexts:

1. Persian Empire: The Persian Empire, under King Xerxes I (referred to as Ahasuerus in the book), was a vast and multicultural empire that stretched from India to Ethiopia. The Jews were one of many minority groups living under Persian rule, which is why they are depicted as a minority subject to royal decrees.
2. Jewish Diaspora: Jews in the diaspora faced challenges of maintaining their cultural and religious identity while living in foreign lands. The story reflects this tension, as Esther, a Jew, initially hides her identity in the Persian court, but later reveals it in order to save her people.
3. Persian Court Life: The book provides insight into the lavish and hierarchical nature of the Persian court, with its complex protocols and customs. This is seen in the king’s opulent banquets, the selection of Esther as queen, and the procedures Esther follows to approach the king.
4. Threat of Annihilation: The central conflict of the book revolves around the existential threat to the Jewish people, driven by Haman’s decree for their destruction. This reflects a broader theme of anti-Semitism and the precarious position of Jews in foreign lands throughout history.
5. Religious Identity in a Foreign Land: Though God is never explicitly mentioned in the Book of Esther, the narrative emphasizes the importance of Jewish identity, community solidarity, and divine providence. The Jewish practices of fasting and communal prayer are seen, even if overt religious language is absent.

The Book of Esther was likely written to encourage and strengthen Jewish identity in the diaspora. It highlights themes of divine protection, human courage, and the survival of the Jewish people against overwhelming odds. The book also serves as the foundation for the Jewish festival of Purim, which commemorates the Jews’ deliverance from Haman’s plot. In this context, Esther is a story of hope, reminding readers that God’s care for His people is present even in foreign lands and in difficult times.
