The continental system was meant to create a blockade for British trade

Explanation:

According to this continental system, ships arrival from Britain were not permitted to enter the ports which were controlled by the French. By doing so, colonial goods could take a hit. Although there was some damage being done to the British economy, exports dropped drastically from 55% to 25%.

The continental system created by Napoleon I to damage the British trade. This was done after Britain blocked the French navy from functioning in the French coast. This system was implemented through the Berlin Decree in 1806.
