Tondo is a district of Manila, Philippines. The locale has existed prior to the arrival of the Spanish, referred to as "Tundun" in the Laguna Copperplate Inscription. One of the most densely populated areas of land in the world, Tondo is located in the northwest portion of the city and is primarily residential-industrial in nature. Tondo is known for being one of the poorest and most underdeveloped districts of the country. Many of the city's slums are found in this area. It is the birthplace of former president Joseph Estrada, King Of Comedy Dolphy, Actress and Comedian Angelica Panganiban, Businessman and Politician Manuel Villar, Manila Mayor and Gatpuno Antonio Villegas, and Andres Bonifacio, the leader of the Katipuneros.
Kingdom of Tondo 
The former region of Tondo is over eleven hundred years old. Historically, Tondo already existed in the year 900 AD according to the Laguna Copperplate Inscription, a legal document written in Kawi now housed in the National Museum of the Philippines. According to this document, Tondo was ruled by person called Jayadeva who holds the Sanskrit title Senapati or "admiral".
Tondo was ruled by a line of Lakan until the Spanish conquest.
Colonial period 
After the Spaniards conquered the City in 1571 AD, Tondo was initially included in the creation of the Province of Pampanga, the first colonial province carved out of the former Sultanate. In census conducted by Miguel de Loarca in 1583 AD, Tondo was reported to have spoken the same language as the natives of the province of Pampanga. Institute of National Language commissioner Jose Villa Panganiban once wrote that the dividing line between Kapampangan and Tagalog was the Pasig River, and that Tondo therefore originally spoke Kapampangan. Tondo eventually became a separate province in the later half of the Spanish colonial era.
Tondo was one of the first provinces to declare rebellion against Spain in year 1896. In 1911, under the American colonial regime, there was a major reorganization of political divisions, and the province of Tondo was dissolved, and its towns given to the provinces of Rizal and Bulacan. Today, Tondo just exists as a district in the City of Manila.
