Today, it encompasses several palaces and museums, showcasing Iranian art, history, and royal artifacts.

This era is known for its significant cultural and artistic developments, including distinctive architecture, painting, and the introduction of photography, as well as Iran’s increasing encounters with Western powers. Despite political decline and territorial losses, the Qajar period left a lasting legacy in Iranian culture, particularly through landmarks like Golestan Palace in Tehran.

Its name reflects the Palestinian concept of steadfastness, and the effort continues a history of similar actions, such as the 2010 Gaza Flotilla incident.
Freedom Flotilla Coalition
The Freedom Flotilla Coalition is an international alliance of activist groups that organizes civilian ships to challenge the Israeli naval blockade of the Gaza Strip, aiming to deliver humanitarian aid and draw attention to the plight of Palestinians. Its history includes the 2010 Gaza flotilla raid, where Israeli forces intercepted the Mavi Marmara, resulting in the deaths of nine activists and sparking global controversy. The coalition continues to coordinate voyages despite legal and logistical obstacles, advocating for freedom of navigation and an end to the blockade.
2010 Gaza Flotilla
The 2010 Gaza Flotilla was a humanitarian aid convoy organized by activists to break the Israeli-Egyptian blockade of the Gaza Strip. On May 31, 2010, Israeli naval forces boarded the lead ship, the *Mavi Marmara*, resulting in a violent clash that left nine Turkish activists dead and sparked international condemnation. The incident highlighted the ongoing Israeli-Palestinian conflict and the humanitarian crisis in Gaza, leading to increased scrutiny of the blockade.
