thumb|upright=1.35|The traditional "Jolly Roger" flag of piracy
I can see the context provided is only an image caption about a pirate flag, which doesn't contain enough information to write an accurate two-sentence overview of sea piracy covering what it is and why it matters. I would need additional context with substantive information about sea piracy to fulfill this request accurately.

Piracy is an act of robbery or criminal violence by ship or boat-borne attackers upon another ship or a coastal area, typically with the goal of stealing cargo and valuable goods, or taking hostages. Those who conduct acts of piracy are called pirates, and vessels used for piracy are called pirate ships. The earliest documented instances of piracy were in the 14th century BC, when the Sea Peoples, a group of ocean raiders, attacked the ships of the Aegean and Mediterranean civilisations. Narrow channels which funnel shipping into predictable routes have long created opportunities for piracy, as well as for privateering and commerce raiding.
