It is nicknamed "The Queen of the Zibans", "The Door of the Desert" or "The Saharan Nice" because of its location at the beginning of the Sahara Desert. Due to its geographical location, its climate and natural resources, particularly farming, Biskra has always been a crossroad between the cities in the north and south. It has seen the passage of several civilizations, from the Romans and the Arabs to the French.
In 1844, Biskra became a French garrison, which saw fighting during rebellions in 1849 and 1871.
Currently the city of Biskra has 28 neighborhoods, including the three principal neighborhoods of Korra, City 60 Logements, and Equipment Zones. It is in the southern part of the Algerian rail system, and has become a popular winter resort.

## Etymology

The city has been known by many names, including Biskra, Sokkra, Vescra, Vecera, Vescera, Adbesran. Historians do not agree on the origins of the current name. Some say its name comes from "Vescera", which means "station" or "place" of commercial exchange, due to its location connecting north and south. The Roman leader Betolimih Benyouba named it "the river of destiny" because of the Sidi Zarzour (its current name) that crosses the city.
Some researchers say that its name was derived from the ancient Roman name "Adebesran" because of the geothermal source that is located near the city, known as Salhine Hammam. Other sources say that the name comes from the word "Sokkra" because of the quality of the sweet dates in the city's oases. Still others claim that the current name was given to the city by the Carthaginians.
In honor of the city, the name was given to an oasis, Biskra Palms, near Palm Springs, California.

## History
### Gaetuli

The Gaetuli first appeared in North Africa during the 3rd millennium BC. They settled in a large territory south of the Roman provinces of Africa and Mauritania. According to the Greek historian Strabo, they were the most numerous people of North Africa yet the least known. Among the oldest references to the Gaetuli are those of the Carthaginians, who indicated that the Prince of the Gaetuli proposed to marry Élyssa (or Dido for the Romans), the founding queen of Carthage (present-day Tunisia) around 815 BC. However, references in ancient Egypt of certain tribes go back to 1350 BC, during the reign of Akhenaten of the eighteenth dynasty, speak of cattle trade with this people.
The Gaetuli are probably the origin of the Berber calendar, which begins around 943–949 BC, which would be after the victory of a coalition of Gétules over the Egyptians. This coalition, formed by the North African tribes, left southwestern Algeria, increasing its force as it passed through North Africa. The coalition led by Shoshenq (Berber name: Sheshnaq) defeated Pharaoh Psusennes II. Following this victory, Sheshnaq married the pharaoh's daughter, settled on the throne of Egypt under the name of Sheshonq in 952 BC, and founded the 22nd Dynasty. This biblical event is mentioned in the Old Testament, which speaks of the pillaging of this leader of the Machaouach tribe.
While traversing the desert, the Gaetuli arrived with the Taureg at Tassili, where they stayed for an extended time and subsequently mixed with the Tuareg and learned the Tamazight language for cultural and commercial exchanges. However, the Gaetuli eventually began to feel out of place and decided to continue north.
In Algeria, they settled at the edge of the Aures, where they posed problems to Roman infiltration in the 3rd century BC as they were stellar horsemen and became dreaded in combat. It was necessary to involve a late Roman politician, Gaius Marius, to negotiate exploration of the South against concessions of agricultural land around Cirta and Setifis, at the time under Roman rule; a trick of dispersing them and so diminished in their strength. Thus, the Gétule were occupied by the Romans.

### Roman colonization

The city of Biskra experienced many violent wars during the Roman colonization, including the resistance war led by the Berber leader Tacfarinas, followed by his successor, the militant Jugurtha "Youghorta". With the help of the inhabitants of the city, who provided human and material support, Jugurtha destroyed the Roman army at the end of the so-called Numidia region.

### The Vandals in the 4th century

The Vandals "Oundals" invaded the city of Biskra and occupied all its land, but the resistance and continuous fighting of its inhabitants forced the Vandals to integrate with them. After a few decades, the Romans took over the city, where they built obstacles to protect themselves from the vengeance of the population.

### The arrival of the Arab conqueror Uqba ibn Nafi al-Fihri in the 7th century

They remained with such vigilance until the arrival of the Arab conqueror Uqba ibn Nafi al-Fihri in the 7th century AD. During this period, the whole area came under the Arab-Muslim monarchy. After 20 years of conquest, Uqba ibn Nafi died in 683 AD when he returned from Morocco with his army. His death was organized by an ambush mounted by his adversary, the Numidian prince (Berber) Koceila and his army at Tahouda, a small village located 5 km from the oasis "Sidi Okba". His body was buried in the mosque of the city that took his name. According to the imam of this mosque, it contains more than 300 tombs and is the 4th holy place of Islam, after Mecca, Medina and Aksa.
In the early 10th century, Biskra and the entire Ziban area were conquered by the kings of Beni Hammad.

### The Hillal Bannis in the 12th century

Followed by the Kabyla of Elathbend banished Hilal (Hilalian Arabs) who removed and confiscated the property of the inhabitants. They asked for the help of the Almohads of the kingdom of Marrakech in the 12th century.

### The Hafsids in the 14th century

In the 14th century, the Hafsid arrived in Tunisia and Algeria. Biskra became an important hub for the Hafsid of Tunisia where it remained under lure monarchy and direction for a long time then under the authority of the Marinid Sultanate of Fez and banned Abd-Elouadi and the Znatiyin of Tlemcen.

### The conquest of the city by the Turks in 1541

In 1541, the Turks began their conquest of the city under the direction of Hocine Agha who defended the city of Algiers at the time and brought out the strength of Charles Compte of the latter.
The Ottoman Empire remained in the city for three centuries until the French colonized it.

### French colonization from 1844

After the French conquest of Biskra in 1844, the site was fortified to secure the area against uprisings. El-hadj Mohammed Esaghire Elokbi, as the successor to El-Emir Abdelkader, waged continued war against the French, attacking the French forces under Lamoriciere on 23 December 1847. Elokbi also opposed the Ben Ghana clan as well as Ahmed Bey's claim as ruler of Constantine. Resistance continued in the Ziban and Aurès Moufrntains.
In Biskra the local chief Bou Zian rallied the people against the palm tax, seizing the moated fortification of Zaatcha 20 km from Biskra. The French marched on Zaatcha [fr], laying siege for months. It finally fell after 53 days of attacks by a French force of 7,000 troops. Bou Zian was killed. The French counted the loss of 2130. French control nonetheless remained tenuous when attacks were mounted again in 1879 at El-kamri.
Some 100 years after the battle of Zaatcha, in 1954 Biskra was again the scene of anti-French assaults during the Algerian War of Independence where house-to-house battles cost many lives.
