The history of Cambridge is rooted in the 1st century AD, when the Romans constructed a fortified fort known as Duroliponte on Castle Hill. The choice of location was dictated by strategic necessity: there was a convenient crossing point over the river, which was then called the Granta. By the time the "Domesday Book" was compiled in 1086, the settlement was already a significant centre. The city's name evolved from the Saxon Grantebrycge ("Bridge over the Granta") to its modern sound, with the river later being renamed the Cam to correspond with the city's name.
Several key factors influenced the establishment and prosperity of the city:
- River Trade: The River Cam provided access to the sea via the port of King's Lynn, turning the city into a vital logistical hub for the transport of grain, wool, and other goods.
- Crossing Monopoly: Control over the only bridge in the area allowed for the collection of tolls and strengthened the economic influence of the region.
- Military Significance: Due to its location on the border of East Anglia, the city played an important role during both the Roman era and the Viking age.
The key event that defined the city's destiny was the year 1209. A group of scholars, having left Oxford due to a conflict with local residents, found refuge in Cambridge. This marked the beginning of the formation of one of the most prestigious universities in the world. Parallel to science, the economy also developed: the medieval Stourbridge Fair held here was considered one of the largest in Europe and attracted merchants from across the continent, cementing Cambridge's status as a thriving city.
