About Dayang Kalangitan
Dayang Kalangitan (or Kaylangitan) ascended as the Queen of Tondo in the 14th century, after her father died without a male successor. She was considered to be one of the more powerful rulers of the kingdom that spanned swaths of land around the Pasig River, enlarging the kingdom's territory. When Sultan Bilkiah of Brunei invaded Manila, she married his son, Gat Lontok.
