A blockade is the act of obstructing or preventing access to a particular place, especially a port, harbor, or country, usually by military force.
It can also refer to an obstruction or impediment that prevents progress or activity of any kind. Blockades are often employed during wartime to cut off supplies and communication, aiming to weaken the enemy.
Furthermore, a blockade can be legally declared, requiring neutral parties to respect its existence and avoid violation.
Symbolically, a blockade can represent any form of deliberate hindrance or barrier to advancement.
