Marley

Māre (マーレ) is a nation inhabiting the expansive continent to the west of Paradis.

Social structure
Marley is a far developed land comparing to the society within the Walls, with its technological level roughly comparable to early 20th century. There are civil transports powered by battery and fossil-fuel, such as blimps and automobiles, although it seems to be available only to the wealthy, non-Eldian population. Electricity seems to be in use, as there are loudspeakers mounted on the walls surrounding the Liberio Internment Zone.

Military
The Marley armed forces technologically resembles an early 20th century military. It is a rapidly developing force which is mentioned to have made incredible advancements in military technology in recent years. These advancements is shown clearly by the triplanes and an ironclad-style warship it possesses, although it is unclear if the force has dedicated air and navy branches. Its soldiers are equipped with an unknown type of long firearm (possibly bolt-action rifles) and revolvers.

Adding to its conventional force, Marley also possess seven Titans which assure its position as a world power. This power is eclipsing, however, as advancement in technology are beginning to undermine the military importance of Titans. The Marley government is aware of it, therefore it planned to conquer Eldia in order to take over the supposedly immense fossil resource laying beneath the island, continuing its military supremacy in the new era. The plan was hindered by King Fritz's threat of unleashing Wall Titans upon the world.

Public Security Authorities
The Public Security Authorities is responsible for controlling movement in and out of the Liberio Internment Zone. It seems to be a brutal but undisciplined force, as one of its men viciously beat a young Grisha Yeager for failing to produce an exit permit, while another soldier sadistically killed Fay by unleashing a horde of dogs upon her. The same two members took naps nearby the blimp airfield while on duty. The role and behavior of its troopers seems to make it analogue to the Military Police within the Walls.
