History.
Etymology.
The name Tondo derives from Tundun, the Old Tagalog name of the city in the Laguna Copperplate Inscription of 900AD (see below), the earliest native document found within the Philippines. Postma, the first to translate the copperplate, believes the term "tundun" originated from the old Indian language Sanskrit, which was used alongside Old Malay as a language of politics and religion in the area at the time. Before this landmark discovery, several theories (however incorrect now) existed:
Philippine National Artist Nick Joaquin suggested that it might be a reference to high ground ("tundok"). French linguist Jean-Paul Potet, however supposed that the River Mangrove, Aegiceras corniculatum, which at the time was called "tundok" ("tinduk-tindukan" today), was the most likely origin of the name.
Tondo in early Philippine history.
The region of Tondo has been settled by humans for over 1,100 years. Historically, Tondo already existed in the year 900 AD according to the Laguna Copperplate Inscription, a legal document that is the earliest document in the Philippines, written in Kawi now housed in the National Museum of Anthropology. According to this document, Tondo was ruled by an unnamed person who held the Sanskrit title of senapati or the equivalent of an admiral. Tondo also had influence all the way to the modern-day province of Bulacan particularly around Lihan (Malolos) and Gatbuca (Calumpit).
Tondo was ruled by a line of lakan until the Spanish conquest.
Colonial Period.
After the Spaniards conquered Tondo in January 1571 they established the Province of Tondo which covered many territories in Northern Luzon particularly Pampanga, Bulacan and Rizal (formerly called Morong), with the city of Manila as its center.
In census conducted by Miguel de Loarca in 1583 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 also wrote that the dividing line between Kapampangan and Tagalog was the Pasig River, and that Tondo therefore originally spoke Kapampangan. although Fray Isacio Rodriquez's Historia dela Provincia del Santisimo Nombre de Jesus de Filipinas stated that Provincia de Tagalos which is Tondo covers all the territories of the future Archdiocese of Manila.
Prior to the establishment of the Province of Bulacan in 1578 Malolos and Calumpit were also included in the territory of Tondo as its "visitas". In 1800, the Province of Tondo was renamed to Province of Manila.
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.
Contemporary period.
Slums developed in Tondo along the Pasig River. Authorities sought to improve housing conditions on these areas without condoning the action of squatting committed by the slums' residents. In the 1970s, the World Bank provided funds to improve conditions in Tondo which led the increase of rent prices and a property boom in the area. These caused the poor to be marginalized. The slums that were upgraded were legalized but these areas remain vastly different from other parts of Manila with higher population density, more irregular road and plot patterns, and uncontrolled housing. 
In the 1987 constitution, Tondo split into two congressional districts of Manila making the first district to the west while the second district in the east. Paco also split by fifth and sixth congressional districts which the fifth in the south and sixth in the north.
Economy.
Tondo hosts the Manila North Harbor Port, the northern half of the Port of Manila, the primary seaport serving Metro Manila and surrounding areas.
The area also hosted Smokey Mountain, a landfill which served Metro Manila and employed thousands of people from around 1960 until its closure in the late 1990s. The dumpsite served as a symbol of poverty even at least two decades since its closure.
Demographics.
Urbanization as well as the Lina Law which favors squatters over land owners has resulted in Tondo being one of the most densely populated areas in the world at .
Crime.
Tondo has developed a reputation for criminality and poverty. In 2010, Manila records state that Tondo has the highest criminal rate in the whole city with the most common crime being pick pocketing.
Culture.
The district celebrates the feast of the Santo Niño de Tondo annually in January, which is dedicated to the image of the Santo Niño housed within the 16th century Augustinian Tondo Church. The Lakbayaw Street Dance Festival, a competition among Ati-Atihan groups and school, local and religious groups, served as the climax of the feast.
