North Sumatra is a province of Indonesia in the northern part of the island of Sumatra. Its capital and largest city is Medan, on the east coast. The province borders Aceh to the northwest, Riau to the southeast, West Sumatra to the south, the Indian Ocean to the west, and the Strait of Malacca to the east, with a maritime border with Malaysia.

North Sumatra has many people, with around 15.8 million living there. It is Indonesia's fourth most populous province and the most populous outside of Java Island. The province covers a large area and is the third-largest on the island of Sumatra.

The region is home to many different ethnic groups, including the Malay people along the east coast, several Batak groups in the west and central highlands, and the Nias people from Nias Island. There are also communities of Chinese, Javanese, and Indian peoples whose ancestors came to Sumatra during Dutch rule.

One famous feature of North Sumatra is the Toba supervolcano, which created Lake Toba. This huge eruption happened many years ago and was one of the largest in Earth's history.

History

Prehistoric era

Early people in North Sumatra were some of the first groups on the island. They lived during a time called the Middle Stone Age. These people mostly ate snails and clams and left behind piles of shells, which can still be seen in some areas today.

Around 1000 BC, new groups of people arrived from mainland Southeast Asia. They lived along the rivers and coasts, fishing and farming. Later, people from Taiwan and the Philippines also arrived, bringing new ways of life.

Early historic era

The coast of North Sumatra became a place where traders from India and China visited often. They came for valuable items like camphor. By the 1300s, a kingdom called Aru was established on the coast. Farther inland, near Lake Toba, Batak people lived in their own kingdoms.

Kingdom, sultanate, and colonial era

Over time, many kingdoms formed along the coast and in the highlands. These kingdoms sometimes fought among themselves. This made it easier for outside powers like Aceh and the Dutch to influence the area.

The Dutch began to take control in the 1800s. They established plantations and brought in workers from other parts of Indonesia and Asia. This changed the makeup of North Sumatra’s population.

Independence and contemporary era

After World War II, North Sumatra became part of the newly independent Indonesia. In 1950, it was officially formed as a province, combining several smaller regions. Since then, it has grown and developed as an important part of Indonesia.

Geography

North Sumatra is a province in Indonesia on the island of Sumatra. It lies between the Indian Ocean and the Strait of Malacca. It borders Aceh to the northwest and Riau and West Sumatra to the southeast.

The land along the coast is flat, and this is where the capital city, Medan, is located. Further south and west, the land rises into the Bukit Barisan mountains. These mountains surround Lake Toba, a big lake formed from an old volcano. There are also many islands off the west coast, such as Nias and the Batu Islands.

The area has active volcanoes, like Mount Sinabung. It also has important natural spaces such as Gunung Leuser National Park and Batang Gadis National Park. Some forests have been damaged by illegal activities.

Governance

The capital of North Sumatra is Medan, and it is led by a governor. In the past, leaders managed all of Sumatra from 1945 to 1950. Then, North Sumatra included Aceh until 1956, when Aceh became its own province.

Administrative divisions

North Sumatra is divided into 25 regencies and 8 cities. It started with fewer areas, but new ones were added over time. These areas are split into smaller parts called districts and villages.

Tapanuli Region

This part of North Sumatra is in the southwest and includes many smaller islands and parts near Lake Toba.

East Sumatra Region

This northeastern area of North Sumatra includes several regencies and cities, with new ones formed from older areas over time.

The region also has many small islands nearby.

National Electoral Districts

North Sumatra has three electoral districts that help choose representatives for the People's Representative Council. Each district picks 10 members, so North Sumatra sends 30 members in total.

  • The North Sumatra I Electoral District includes parts of Deli Serdang and Serdang Bedagai, along with the cities of Medan and Tebingtinggi.
  • The North Sumatra II Electoral District covers many regencies and cities in the region.
  • The North Sumatra III Electoral District includes the remaining regencies and cities.
