According to folklore, the word Blora is derived from the word belor which means mud. It then evolved into mbeloran, then contracted to blora. This folk etymology could partly explain the origin of this name, as the word evolved from Old Javanese instead of the modern belor. See the explanation below.
The word Blora means low, watery ground. The name was derived from way and lorah combined (wailorah), which means water and cliff, respectively. During its evolution, the Modern Javanese language evolved voiced plosive [b] from the previous approximant [w] in Old Javanese in the same manner as in Persian. Modern Javanese has also monophthongized Old Javanese "ai" or "ay" into "e", and lost its h's in many places, almost similar to that of French from Latin. Therefore, wailorah became bailorah, then bailora, and finally blora.
Blora was under the administration of the Duchy of Jipang in the 16th century, which was itself still ruled by the Demak Sultanate at the time. The Duke of the duchy was Arya Penangsang, better known as Aria Jipang. The area under the control of the duchy includes Pati, Lasem, Blora, and Jipang. But, after Joko Tingkir (Hadiwijaya) inherited the throne, the capital was moved into Pajang. After that, Blora was under the Kingdom of Pajang.
The Duchy of Jipang did not rule for long, because it was seized by the Mataram Kingdom. Blora was in the eastern part of the kingdom (Bang Wetan). During the reign of Pakubuwono I (1704–1719), Blora was given to his son, Pangeran Blitar, and appointed as a duke. The area of Blora at that time was 22.5 km2. In 1719–1727, the Mataram Kingdom was led by Amangkurat IV, so Blora was under Amangkurat IV's rule.
When Mataram was under the administration of Pakubuwono II (1727–1749), there was a rebellion led by Mangkubumi and Mas Sahid, Mangkubumi succeeded in controlling Sukawati, Grobogan, Demak, Blora, and Yogyakarta. Finally, Mangkubumi was appointed by the people to be a king in Yogyakarta.
From the Pajang era to the Mataram era, the Blora Regency was an important area for kingdoms. This was because Blora was known for its teak forests. News from Babad Giyanti and Serat Kuntharatama stated that Mangkubumi became a king on 11 December 1749, the day Blora Regency was created. Along with the appointment of Mangkubumi as a king, other officials were also appointed. The leader of the Mangkubumen warriors, Wilatikta, was appointed as the first regent of Blora. Blora's status changed from apanage into a regency on that same day.
The War of Mangkubumi ended with the Giyanti agreement, in 1755, which was known as palihan negari. Because of this agreement, Mataram was divided into two kingdoms, the Surakarta Sultanate under Paku Buwana III, and Yogyakarta, under Sultan Hamengkubuwono I. In the now-divided kingdom, Blora was in the Surakarta Sultanate as part of the Mancanegara Timur area. However, the regent of Wilatikta did not agree to join the sultanate, so he chose to resign from his position.
Resistance by the people against the Dutch, which was pioneered by the peasants, emerged in the late 19th and early 20th centuries. It was caused by the worsening social and economic conditions of the rural population at that time. In 1882, a head tax was imposed by the Dutch, which was very burdensome for landowners (farmers). In other areas in Java, tax increases have led to peasant revolts, such as the Cilegon incident in 1888. Two years later, Saminism, a mystical religious sect, rose from the Randublatung region in Blora and Bojonegoro Regency in 1890, and gained prominence in the early 20th century. Headed by a Javanese peasant, Surontiko Samin, it followed the teachings of the Islamic prophet Adam but owed little to the religion. Stressing the village structure, mysticism, and sexuality, it became an early protest movement and was opposed to the local rulers as much as it was against the Dutch East Indies colonial administration, refusing to pay the new Dutch head tax. After 1907, many followers were detained and arrested by the Dutch. The movement survived until the 1960s.
During the administrative restructuring of Java during 1925–8, Blora briefly became one-half of the new Blora Residency; it was abolished in 1931.
The regency has an area of. Blora Regency consists of both lowland and hilly areas between 20 and 280 metres high above sea level. The northern part of the regency is a hilly area that forms a series of Northern Limestone Mountains as well as the southern area (Kendeng Mountains) that stretches from east of Semarang to Lamongan (East Java). The capital of Blora Regency is located right on the slope of the Northern Limestone Mountains.
Half of Blora Regency's area is forested, especially in the northern, eastern, and southern regions, while the central lowland is mainly used for agricultural purposes (rice fields). During the dry season, most of Blora Regency has a water supply shortage, either for drinking or irrigation, especially in limestone and mountainous areas. In the rainy season, several areas are prone to landslides.
