This is a brief history of blockades in the Hunter Ocean. Blockade winners are indicated in bold. All blockades without defenders (uncolonized) are sinking. All blockades with defenders (colonized) are non-sinking unless noted otherwise. All dates represent the day (in PST/PDT timezone) that the first round began. Only official contenders and defenders are listed. Contenders' allies are not listed, nor are unallied defenders.
