Answer 1

As the time passed in Ancient India, Magadha had become the centre of political activity in north India and powerful among all the kingdoms. Rajagriha was the capital of Magadha. Bimbisara ruled for 52 years from 544 B.C. to 492 B.C. He was imprisoned by his son Ajatshatru (492- 460 B.C.) and murdered. Bimbisara was the ruler of Magadha .He came from the Haryanka dynasty.

Through matrimonial alliances he strengthened his postion and prosperity. His first alliance was with the family of Kosala, the lady named Kosaladevi. He was given the Kasi region as a dowry. Then, Bimbisara married a princess of the Licchavi family of Vaisali named Chellana. Now this alliance secured him the safety of the northern frontier. He again married Khema of the royal house of Madra in central Punjab. He defeated Brahmadatta of Anga and captured his empire. He had good relations with Avanti. 

Ajatshatru (494 - 462 B.C.)
Ajatshatru killed his father and snatched the kingdom. Throughout his time he followed an aggressive policy of expansion. This pushed him towards Kashi and Koshala. There began a so long disturbance between Magadha and Koshala. The Koshal king was forced to purchase peace by giving his daughter in marriage to Ajatashatru and also giving him Kashi. He also declared war against the Lichchavis of Vaisali and conquered the Vaishali Republic. This war continued for sixteen years.

अजातशत्रु द्वारा मौत के घाट उतार दिया गया। अजातशत्रु ने 492 ईसा पूर्व से 460 तक मगध पर शासन किया और विजय और विस्तार की नीति का पालन किया। उसने कोसाला के राजा सहित अपने पड़ोसियों को हराया। इसकी शुरुआत अलदेवी की मौत से हुई। उसके भाई (जो अजातशत्रु के चाचा थे) ने काशी पर कब्जा कर लिया था, जिसे बिंबिसार को दहेज के रूप में दिया गया था। इससे कोसला और उकठा के बीच युद्ध हुआ। अजातशत्रु ने काशी पर कब्जा कर लिया और छोटे राज्यों पर कब्जा कर लिया। उन्होंने वैशाली के लिच्छवियों को भी नष्ट कर दिया। उसके तहत मगध उत्तर भारत में nt शक्तिशाली राज्य बन गया और इसकी शक्ति दूर-दूर तक महसूस की गई। अंबिसारा अपने बेटे अजातशत्रु के विद्रोह का शिकार हो गया। वह अजातशत्रु द्वारा कैद किया गया था, उसके कदन, उदयन द्वारा सफल हुआ था। लिडाना के शासनकाल की एक महत्वपूर्ण घटना पाटलिपुत्र (पटना) शहर की नींव थी, जो तीन नदियों, गंगा, सोन और गंडक के संगम पर स्थित थी। यहाँ से, वह गंगा के मैदान और गंगा के किनारे व्यापार को और अधिक प्रभावी बनाए रख सकता था। उसने पाटलिपुत्र को अपने साम्राज्य की राजधानी बनाया। उदयन और जो चार राजा थे, वे बहुत शक्तिशाली शासक नहीं थे। इनमें से अंतिम को मगध के लोगों द्वारा उखाड़ फेंका गया माना जाता है। इसके बाद शिशुनाग और उसके वंश का शासन था। नंदों के अधीन, मगध एक बार फिर शक्तिशाली हो गया।
