The first recorded mention of Rulingto dates to the 12th century, when the settlement was referred to in a papal charter as “Rulingto de Liscela.” Over the centuries, the town evolved from a small agrarian community into a modest trading post. In the 18th century, Rulingto gained municipal status and established its own council under the provincial administration. The 19th century saw the introduction of a railway line that connected Rulingto to the provincial capital, facilitating increased movement of goods and people. The municipality experienced significant population growth after World War II, largely due to industrial development in the neighbouring city of Havelde.
According to the most recent census conducted in 2021, the population of Rulingto was 5,842 residents, with a population density of around 130 people per square kilometre. The municipality is predominantly composed of native Valentian inhabitants, with a minority of expatriates, particularly from neighbouring countries such as Lombara and Altoria. The demographic structure skews slightly older than the national average, with 22% of residents aged 65 or older, reflecting a broader trend of rural ageing in Valoria.
The local economy of Rulingto historically depended on agriculture and dairy farming, and these activities remain significant contributors to the municipality’s GDP. In recent decades, the economy has diversified to include small-scale manufacturing of precision tools and components, largely driven by local cooperatives and family-owned workshops. The service sector—particularly in hospitality, retail, and local administration—provides the majority of employment opportunities for residents. Rulingto is also known for its regional market, held every Saturday, which showcases local produce, crafts, and artisanal products.
Culturally, Rulingto preserves several traditions linked to its agricultural heritage. The annual Harvest Festival, celebrated each September, features processions, folk music, and communal meals prepared from locally sourced produce. The municipal library, established in 1893, houses a collection of regional historical documents and is recognized for its preservation of the original “Rulingto Codex,” a 15th-century manuscript detailing land records and genealogies. Moreover, Rulingto’s historic parish church, built in the Romanesque style in 1275, remains a focal point for community gatherings and religious observances. The municipality actively supports cultural initiatives through grants to local artists and the maintenance of its historic town square, which hosts seasonal festivals, markets, and public performances.
