Onitsha has a complex and ancient history. Before the 17th century, the area was known as Ado N'Idu. It was a subordinate district of the Benin Empire. The indigenous people were the Igbo.
Historical accounts suggest the Igbo emigrated from the Benin Empire between 1630 and 1680. A leader named Eze Chima led these people. They sought to establish their own customs and laws. After a conflict with the Benin forces, the people moved to find new land. They eventually reached the Niger River. They named the new settlement Ọ̀nị̀chà Mmílí. This means "Onitsha-on-water" because of the many rivers nearby.
As the settlement grew, it developed distinct social structures. Eze Chima established the Order of Ozo to distinguish nobles. He also created the Onitsha Ofala Festival. This is an annual event where the king meets his subjects.
During the colonial period, British rule changed the city's administration. In the mid-1850s, the city became a trading port for the Royal Niger Company. This growth followed the abolition of slavery and the invention of the steam engine. Later, in 1900, Onitsha became part of a British protectorate. Christian missionaries also arrived and helped build schools and churches.
The population of the city has grown tremendously over time. In the early 1960s, the population was only 76,000.
By 2016, the greater Onitsha area had an estimated eight million people. As of 2025, the city proper has about 5,628,000 residents. The city saw a huge influx of immigrants during the oil boom of the 1970s. This rapid growth has led to many challenges. Much of the building was done quickly without strict zoning regulations. This has resulted in a congested city with many slums.
Onitsha is also known for its cultural and creative influence. It was the setting for the famous Onitsha Market Literature. This refers to a specific type of popular written work. The city is also a major hub for Nollywood films. This is the Nigerian film industry. The writer Chinua Achebe once described the region as a place of great creativity.
However, the environment faces serious issues. The city is considered highly polluted. In 2016, the World Health Organization noted it was the most polluted city in Africa. Rapid urbanization also affects the local landscape and causes erosion.
The climate in Onitsha is shaped by two main seasons. The wet season runs from March to October. It is characterized by warm, overcast, and rainy weather. The dry season lasts from November to February. This season is hot and partly cloudy.
During the winter, the Saharan harmattan winds blow through the region. These winds create haze and reduce visibility. Temperatures usually stay between 19 and 31 degrees Celsius. The weather is influenced by trade winds from the Atlantic International Convergence Zone. This climate supports the ongoing life and movement within this massive metropolitan hub.
