Around 185 BCE, the Mauryan dynasty was replaced when Pushyamitra Shunga assassinated the last Mauryan ruler, Brihadratha, and assumed power—marking a major political transition centered on the former imperial capital region.
Theravāda tradition places the Third Buddhist Council at Pataliputra around 250 BCE, associated with efforts to purify the sangha and linked to Ashoka’s broader patronage of Buddhism (though historical details are debated).
Under Ashoka (3rd century BCE), Pataliputra remained the core imperial capital; traditions and material culture associated with Ashokan-era governance and monumental building are strongly tied to the city and its environs.
Bindusara succeeded Chandragupta and ruled from Pataliputra, maintaining the city’s function as the empire’s political hub during continued consolidation and expansion.
Later Greek writers (e.g., Strabo quoting Megasthenes) portray Pataliputra as strongly fortified—famously with timber defenses—evidence often discussed alongside the Mauryan-era wooden remains found in Patna excavations.
Greek ambassador Megasthenes resided at Chandragupta’s court in Pataliputra and later described the city (in Indika, preserved via later authors), providing a key external account of its scale, governance, and fortifications.
After establishing Mauryan rule (c. 321 BCE), Chandragupta governed from Pataliputra (near modern Patna), consolidating the city’s role as the administrative center for a rapidly expanding, centralized empire.
Excavations at Bulandi Bagh (Patna) revealed major Mauryan-period remains, including a monumental stone capital (the “Pataliputra capital”) reported from Waddell’s 1895 work at the palace area—often discussed as evidence of elite architecture in the capital zone.
D. B. Spooner’s early 20th-century excavation campaign at Kumrahar (part of ancient Pataliputra’s archaeological landscape) identified Mauryan-era architectural remains, initiating systematic study of monumental construction in the capital area.
Excavations at Kumrahar traced pillar locations for an 80-column hypostyle hall (often linked to Mauryan imperial functions), highlighting the scale of capital projects and possible timber superstructures supported by stone pillars.
The Didarganj Yakshi sculpture was recovered in 1917 near Patna, close to the ancient Pataliputra area; while its exact date is debated, it remains an important object in interpreting early monumental art traditions associated with the Mauryan capital’s broader cultural milieu.
ASI excavations (1926–1927) exposed long stretches of a wooden palisade at Bulandi Bagh, widely interpreted as part of Pataliputra’s timber fortifications described in classical sources—tangible evidence of Mauryan urban defense engineering.
