Republic (1628-1793)

Revolution and occupation by Franqueterre (1793-1815)

The 1789 revolution in Franqueterre also led to social unrest in Atreisia. Despite Atreisia being a republic, the nobility and large trade guilds dominated politics. Liberals opposed the protectionism and authoritarian nature of the republic, while the left criticized the suppression of the lower classes. In the late summer of 1789, there were uprisings in various cities, particularly in the north. Republican forces managed to suppress them, causing significant liberal and left-revolutionary figures like Emmanuel Robbenjager, Niels Koopmans, and Johannes Papen to flee to Franqueterre. From there, they organized resistance against the conservative republic. In Franqueterre, a revolutionary force was mobilized, which invaded Atreisia in May 1793. After several defeats for the revolutionary troops, the army of Franqueterre came to their aid. Atreisia was largely conquered, except for parts of the Aulpen. Robbenjager perished in one of the battles. On July 17, 1793, the triumvirate of the liberal Niels Koopmans and the left-revolutionaries Johannes Papen and Karel Bouchez was appointed as the head of state.Before long, there was significant discord within the triumvirate. Supported by trade guilds, a faction of the nobility, and large urban industry guilds, the liberals staged a coup on August 26, 1793. However, Franqueterre continued to support the left-revolutionary factions, and in the tumultuous month of September 1793, Franqueterre troops occupied most strategic points in Atreisia. On January 1, 1794, the majority of Atreisia was formally annexed by Franqueterre. Just like in Franqueterre itself, a turbulent period followed between 1794 and the end of 1796, often referred to as 'the terror', during which various political factions were dealt with. Many liberals were executed, as were moderate and pacifist factions within the left-revolutionaries. Some significant liberal politicians managed to escape to Lentia or to the city of Beren, which was not occupied by Franqueterre.

Until 1815, a significant portion of Atreisia remained part of Franqueterre. Following the republican period, the Franqueterre Empire took over. Atreisia was dragged into various coalition wars, leading to a growing resentment among the population towards Franqueterre. It wasn't until the defeat of the Emperor of Franqueterre in 1815 that Atreisia could secede once again.Franqueterre occupied several major mountain valleys, but the majority of the Aulpen remained unoccupied during the occupation period. The Bondsraad established itself in the city of Beren in 1794, and from there, what remained of Atreisia was governed as a republic.

Constitutional monarchy (1815-)

Under the influence of Kalm, Lentia, and Ingerland, Atreisia regained formal independence with the coronation of Boudewijn I as king on September 4, 1815. The abolition of the republic and the installation of Boudewijn were crucial conditions for this independence, but the liberal politicians in exile and the unoccupied Aulpen Bondslands were able to enforce a very liberal constitution with a constitutional monarchy.


Physical Geography

Atreisia, a captivating land, is defined by the Aulpen mountain range at its heart. These majestic mountains, forming the central backbone with a general east-west direction, interlink with adjacent ranges in neighboring territories. Comprising central massifs surrounded by fouthill massifs, the Aulpen dominates the landscape.

To the north of the Aulpen, a diverse expanse unfolds—eroded low mountain chains, expansive plateaus, and sedimentary basins characterize this region. At the northernmost edge lies the Neeve River, carving through its sedimentary basin, offering a blend of rugged terrain and serene plains, enhancing Atreisia's scenic allure.

Stretching along the northwest coast are the eastern extensions of the Morcanol Bay. This coastal belt encompasses a mosaic of coastal marshlands, dominated by sandy beaches.

To the south of the Aulpen, a similar topographical tapestry emerges—eroded low mountain chains, undulating plateaus, and interconnected sedimentary basins form part of the larger Ijsne River basin, contributing to Atreisia's diverse geographical makeup.

Nature Reserves and National Parks

Atreisia has XX national parks:

Koksland National Park

Located in the northern region of the Aulpen mountain range, Koksland National Park features a high mountain plateau nestled between two ridges, with the ridges not significantly higher than the plateau itself. Forests dominate the lower western areas, while higher elevations boast alpine meadows, along with numerous smaller lakes and peatlands. The park offers outstanding hiking opportunities, especially for multi-day treks, allowing visitors to explore its diverse terrain. Wildlife abounds, including bears, wolves, lynxes, deer, chamois, and marmots. However, the park is renowned primarily for its unique flora and hosts a few rare fish species. Known as a habitat for breeding birds, notable species include the golden eagle, bearded vulture, snow finch, and whooper swan. Within the park's boundaries lies Bevermeren, a small tourist village functioning as an enclave.

Regional Geography

Atreisia is a country with a large diversity of cultural and natural landscapes. Below we detail on the typical properties of those landscapes:

Bondsland Beren

The Bondland of Beren, named after the former Duchy of Beren, once a prominent seat of power, boasts its capital in the city of Beren. Positioned at the confluence of the Aar and Murge rivers, the city of Beren stands as the thriving social and economic epicenter, renowned for its plethora of monuments, inviting cityscape, esteemed university, and robust banking sector.

The State of Beren, nestled within the mountainous expanse of the "Aulpen," is characterized by its dramatic terrain and expansive valleys. Notable among these valleys are the Murge, Linten, Witte Traune, and Rook valleys, each contributing to the state's diverse landscape. Towards the eastern boundary, the state extends to encompass the Grootmeer, a glacial overdeepened mountain lake, adding to the region's natural allure. Within this stunning setting, other significant cities within the state include Wildburg, Rozenburg, and Lintenbrug, each contributing to the cultural and economic diversity of the region. Beren is celebrated for its picturesque landscapes featuring towering mountain ranges, sprawling plateaus, and iconic peaks such as Hemelspits (4310 m) and Koningskroon (4572 m), along with prominent plateaus like Wolfsplateau and Koksland. This stunning setting of Beren is also home to a rich variety of wildlife, including deer, bears, ibexes, and majestic birds like the golden eagle.

While historically reliant on mining, forestry, and agriculture, the modern economy of Beren thrives on specialized industries, particularly in leisure products (skiing, skateboarding, cycling), outdoor apparel, dairy products, luxury furniture, and a robust international banking sector. The Murge and Linten valleys serve as hubs for both population density and economic activities.

Renowned as a haven for winter sports and summer outdoor activities such as hiking, mountain biking, birdwatching, mountain climbing, and parasailing, Beren attracts outdoor enthusiasts year-round. Beren city, a hotspot for cultural tourism, draws visitors keen on exploring its historical heritage and vibrant cultural scene.

Major transport routes traverse the Murge and Linten valleys, with Beren city situated along a crucial North-South railway line, complemented by branch lines to smaller valleys and Lintenbrug. Expressways connect the Grootmeer through the Linten valley to Beren city and a second North-South expressway passing through Beren city, linking the two routes.

Historically, Beren's significance stemmed from its influential dukes, fostering a robust economy for centuries, and the famed Beren Legion —a renowned mercenary force from the pre-modern era, often engaged in significant battles.

Bondsland Jorra

Bondsland Westerland

Provincie Watermark: The Watermark Province is a predominantly rural area characterized by flat terrain and numerous villages. Its primary and only city, Waterkampen, serves as the capital and largely functions as a commuter town for Spiedam. Watermark comprises low-lying regions originally formed as coastal marshlands, now repurposed for agricultural use, primarily featuring pastures with grazing cows, contributing to a thriving dairy industry producing milk and cheese. Additionally, there are scattered orchards within the area. The province boasts numerous coastal lakes, some of which have been drained, while those remaining hold significant ecological value. A network of canals and drainage channels crisscrosses the landscape. Along the coastline stretches a wide dune belt, home to a few coastal villages with limited tourism opportunities.
