Ancient and Medieval Indian Rulers

Pushyamitra Sunga founded the Sunga dynasty in 185 BCE after assassinating the last Mauryan ruler, Brihadratha. He was the commander-in-chief of the Mauryan army and established Brahminical orthodoxy, opposing Buddhist expansion. Agnimitra was his son (and the hero of Kalidasa's Malavikagnimitram), while Divakarmaitra and Vasumitra were other figures not associated with founding the dynasty.

The Chola dynasty, under Rajendra Chola I, extended its rule beyond mainland India to include parts of Sri Lanka and the Maldives through their powerful naval expeditions. They controlled most of the Indian Peninsula and established maritime dominance in the Indian Ocean. The other options are incorrect as the Cholas did not control Andaman and Nicobar, Daman and Diu, or Lakshadweep.

Kadphises I (also known as Kujula Kadphises) was the founder and first ruler of the Kushana dynasty in the 1st century CE. He unified the Yuezhi tribes and established the Kushana Empire in Central Asia and Northwest India. Samudragupta, Harsha, and Ashoka belonged to different dynasties - Gupta, Pushyabhuti, and Maurya respectively.

Gopala was the founder of the Pala dynasty in the 8th century CE. He established the dynasty after being elected by various regional chiefs in Bengal and eastern India. The Pala dynasty ruled for over four centuries and was a major patron of Buddhism and Buddhist learning.

The Great Stupa at Sanchi, one of the largest and most famous stupas in India, was originally commissioned by Emperor Ashoka of the Mauryan dynasty in the 3rd century BCE. While later expanded by other dynasties including the Shungas, its core structure and the tradition of stupa-building flourished most during the Mauryan period as part of Ashoka's promotion of Buddhism.

Vishnuvardhana was a prominent ruler of the Hoysala dynasty (c. 1108-1142 CE), known for military campaigns and temple-building. The Chalukyas were his overlords early in his reign, Pallavas were earlier and based in Tamil Nadu, and Mauryas were a much earlier ancient empire (3rd century BCE).

Konganivaram (or Konganahalli) is associated with the Ganga dynasty, who ruled parts of Karnataka. The Gangas were contemporaries and sometimes rivals of the Cholas. Cholas were based in Tamil Nadu, Pallavas were earlier Tamil rulers, and Chalukyas ruled from a different region of Karnataka.

Lakshmanasena, the last major ruler of the Sena dynasty (c. 1178-1206), established his court at Nadia (also known as Nabadwip) in Bengal. The Sena dynasty ruled Bengal from their capital at Nadia, which was a center of learning and culture. Lakshmanasena's reign saw the decline of Sena power with the Turkish conquest.

The Satavahana dynasty ruled in the Deccan region from around 1st century BCE to 3rd century CE. Simuka was the founder, Krishna was a prominent ruler, and multiple rulers bore the title 'Satakarni'. Vijayasena, however, was not a Satavahana ruler but a ruler of the Sena dynasty in Bengal (12th century CE), making him the correct answer to this question.

Pushyamitra Shunga, a Brahmin general in the Mauryan army, assassinated the last Mauryan emperor Brihadratha in around 185 BCE and founded the Shunga dynasty. This marked the end of the Mauryan Empire and the beginning of Shunga rule, which lasted until approximately 73 BCE. Pushyamitra was a patron of Brahmanism and performed two horse sacrifice rituals (Ashvamedha).

Qutb-ud-din Aibak founded the Slave Dynasty (also known as the Mamluk Dynasty) in 1206 after the death of his master Muhammad Ghori. He was a slave of Turkic origin who rose to become a general and then the first Sultan of Delhi. The Slave Dynasty (1206-1290) was the first of the five dynasties that constituted the Delhi Sultanate, and it ruled northern India for nearly a century.

The Saka Era began in 78 AD and is associated with the Kushan emperor Kanishka (or his predecessor Vima Kadphises). While the era was named after the Shakas (Scythians) who had invaded northwestern India earlier, it was Kanishka who formally adopted this calendar system for official inscriptions and coinage. The Saka Era is still used today as the official calendar of India (Saka Samvat) and is the basis for the Indian National Calendar.

Akhenaten (Akhnaton) of Egypt was famous for his religious revolution, promoting monotheism (worship of Aten). Similarly, Asoka underwent a religious transformation after the Kalinga war, embracing Buddhism and non-violence (dhamma). Both rulers shifted from traditional state policies to religious/ethical governance, though their contexts differed significantly.

Chandragupta Maurya is credited with establishing the first organized road network in the Mauryan Empire, including the famous Grand Trunk Road from Taxila to Pataliputra. While Ashoka later expanded and improved this system with trees, wells, and milestones, Chandragupta initiated the infrastructure development.
