Why did Magadha become so powerful?
(i) FERTILE soil of Ganga plain → high revenue; (ii) IRON ORE from Chotanagpur → weapons & ploughs; (iii) ELEPHANTS from forests; (iv) river Ganga as transport; (v) ambitious rulers (Bimbisara, Ajatashatru, Mahapadma Nanda).
Who were Bimbisara and Ajatashatru?
BIMBISARA (r. ~544-492 BCE) of the HARYANKA dynasty — first major king of Magadha; built marriage alliances with Kosala, Vaishali, Madra. AJATASHATRU (r. 492-460 BCE) — son; killed his father; conquered KASHI and VAISHALI; introduced new weapons (mahasilakantaka catapult, rathamushala scythed chariot).
Why was Pataliputra chosen as capital?
Founded c. 490 BCE at the confluence of Ganga + Son + Punpun + Gandak rivers — naturally defended on three sides by water; commanded river trade across the entire Ganga basin.
Magadha's NANDA dynasty — power and wealth?
NANDAS (~345-321 BCE) replaced the Shishunagas; first non-Kshatriya rulers of Magadha (Mahapadma Nanda was of low birth — "ekarat" sole sovereign); famously rich (legendary treasury); maintained massive army (200,000 infantry, 80,000 cavalry, 8,000 chariots, 6,000 elephants per Greek records). Their power scared Alexander's troops at the Beas in 326 BCE — a key reason for Greek mutiny.
Why did Pataliputra succeed Rajagriha as the Magadhan capital?
Pataliputra (founded ~490 BCE by King UDAYIN, grandson of Ajatashatru) sat at the confluence of Ganga + Son + Punpun + Gandak — naturally defended on three sides; controlled river trade across the Ganga basin; Rajagriha was hill-locked and limited.
Bimbisara's marriage alliances — why did they matter?
BIMBISARA (~544-492 BCE) married into 3 powerful royal houses: KOSALA (princess of Pasenadi), VAISHALI (Licchavi princess Chellana — mother of Ajatashatru), MADRA (princess Khema of Punjab). Alliances secured borders and inheritance claims — diplomatic genius before military expansion.
What new weapons did Ajatashatru introduce in his Vajji war?
MAHASILAKANTAKA — a massive catapult that hurled large stones over fortifications. RATHAMUSALA — a chariot with attached scythes/maces that mowed through infantry. These innovations were decisive against the Vajji confederacy's defensive tactics.
What was the Vajji Sangha?
A CONFEDERATION of clans (Licchavis, Videhas, Jnatrikas — Mahavira's clan) ruling from VAISHALI; a "GANA" or "SANGHA" — early form of REPUBLIC. Decisions made collectively in assemblies; no single hereditary king.
How was Vajji different from monarchies like Magadha?
In a SANGHA: many "rajas" (chiefs) governed COLLECTIVELY through assembly; in a MONARCHY: ONE hereditary king. Sanghas were "gana-rajya" (republic); monarchies were "raj-rajya". Vaishali is sometimes called the world's OLDEST REPUBLIC.
Fate of the Vajji Sangha?
Conquered by AJATASHATRU of Magadha (~460 BCE) after long war using new weapons and political subversion. End of the great early republic.
Who were the 8 main clans of the Vajji Sangha?
LICCHAVIS (capital Vaishali), VIDEHAS (capital Mithila), JNATRIKAS (Mahavira's clan, capital Kundagrama), and 5 others. Confederation called "atthakula" (eight clans); largest of the gana-sanghas of the period.
How did the Buddha view the Vajji Sangha?
In the MAHAPARINIBBANA SUTTA, the Buddha lists 7 conditions of Vajji prosperity: (i) frequent assemblies; (ii) decisions in unanimity; (iii) honouring traditions; (iv) respecting elders; (v) protecting women; (vi) honouring shrines; (vii) protecting holy persons. He warned Ajatashatru's minister Vassakara that Vajjis were unconquerable while these held.
