1200 - 1290

The arrival of crusader armies in the early 13th century tested Semigallian political cohesion as never before. Henry of Livonia's chronicle records the Semigallians as formidable opponents who negotiated, allied, and fought across decades. Rather than a simple 'last stand' annihilation, the defining event of 1290 was a strategic withdrawal: a significant portion of the Semigallian population migrated to Lithuania, where Lithuanian archaeology confirms Semigallian settlement in Žiemgala. Those who remained lived under the Livonian Order's authority. The hillforts at Tērvete and Mežotne bear the physical scars of siege and destruction, but the Semigallian story did not end there — it bifurcated into a diaspora thread and a thread of accommodation under foreign rule.

1290 - 1561

Under Livonian Order rule, stone castles rose on or near the former hillfort sites — Dobele (1335-1339), Bauska (mid-15th century) — physically overlaying Semigallian settlement layers with German military and administrative architecture. The Order imposed a manorial economy in which Latvian-speaking peasants worked estates owned by German-speaking elites. Yet the Lutheran Reformation, reaching Zemgale in the 1520s-1540s, created an unexpected opening: the Dobele Lutheran Church (1495, with its famous bell inscribed 'Awaken. Encourage. Comfort.') and Jelgava's Holy Trinity Church (founded 1567) became Latvian-language congregational spaces where folk-calendar practices could survive under Christian names. The material layer of Order-era stone walls and the spiritual layer of Lutheran parish life are both legible today.

1561 - 1795

The Duchy of Courland and Semigallia (1561-1795) was a paradox: a German-speaking court ruling a Latvian-speaking peasantry, yet pursuing maritime ambitions that reached Tobago (1654) and Gambia (1651) under Duke Jacob Kettler. Jelgava (Mitau) became the ducal capital, anchored by Jelgava Palace and the Academia Petrina (1775, first higher-education institution in Latvian territory). Rundāle Palace (1736-1768) and Mežotne Palace (1797) display the Baroque and Neoclassical ambition of the Biron dynasty. Bauska Town Hall (1616, largest in the Duchy) testifies to urban self-governance under ducal authority. The duality is inescapable: these buildings were erected by Latvian hands for German-speaking patrons, and their post-ducal reappropriation — Jelgava Palace as agricultural academy (1939), Rundāle as Latvian-national restoration project — is part of the same story.

1795 - 1918

After the Duchy was absorbed into the Russian Empire (1795), the Baltic German manor-estate system was reinforced rather than dismantled. The empire added its own confessional layer: St. Simeon and St. Anna Orthodox Cathedral in Jelgava (1890-1892, built with Czar Alexander III's support) introduced a Russian Orthodox liturgical calendar running parallel to the Lutheran and folk calendars — a triple temporal rhythm that persists in Jelgava today. Mežotne Palace (1797, Quarenghi-designed Neoclassical) and Academia Petrina (now an observatory and museum) illustrate how Enlightenment and imperial currents reshaped the built environment while leaving the peasant majority's agrarian-ritual world largely unchanged. The folk-calendar survived not in official institutions but in the seasonal practices of Lutheran congregations that kept swinging at Easter, lighting bonfires at Jāņi, and honouring ancestors in autumn.
