Ancient and Medieval Indian Rulers

The Saka Era was founded by Kushan ruler Kanishka I in 78 CE. This calendar system continues to be used by the Government of India for official purposes alongside the Gregorian calendar. The other rulers listed founded different eras: Vikramaditya (Vikrama Era 57 BCE), Ashoka, and Samudragupta were associated with different time periods.

The Satavahanas (also called Satvahanas) ruled from the 1st century BCE to 3rd century CE, making them the oldest dynasty among the options. Rashtrakutas and Chalukyas ruled much later (7th-10th century CE), while Pallavas emerged in the 4th century CE. The Satavahanas controlled the Deccan region after the Mauryan decline.

Most Ajanta caves were excavated during the Gupta period (5th-6th century CE) under the patronage of Gupta rulers and Vakataka kings. This period is considered the golden age of Indian art. The caves were rediscovered in 1819 by a British officer.

The Maurya Dynasty (322-185 BCE) is the oldest among the options, founded by Chandragupta Maurya after overthrowing the Nanda Empire. The Kushan Empire (1st-3rd century CE), Gupta Empire (4th-6th century CE), and Kanva Dynasty (71-26 BCE) all came later. The Mauryas represent India's first major empire spanning most of the subcontinent.

Harihara and Bukka, the founders of the Vijayanagar Empire (1336), were guided by the sage Vidyaranya of the Sringeri Math. He provided spiritual counsel and helped them consolidate the Hindu kingdom against Islamic invaders. Jnaneshwara and Tukaram were later Bhakti saints from Maharashtra, while Ramanuj was a 12th century Vaishnavite philosopher.

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 Chalukya dynasty was established in the southern region of India, primarily in the modern state of Karnataka. They ruled over large parts of the Deccan plateau and were one of the most important dynasties in South Indian history. Northern, Eastern, and Western India are incorrect as the Chalukyas were specifically a southern 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.
