The Tinian March or Tinian Caicova (Rodarian: Caicova Tiniano) is an area of central Lusankya, today split among Torchland, Rodarion, Iron State and Bogoria. Tinian March was coined by the Rodarian geographer Giancarlo Scorza in order to present the Lusankyan Littoral as a unified region and "historic part of Rodarian", placing emphasis on the Tinian partition of Romulan Rodarion at the height of the Empire, when the region constituted Transtenine Caicona.
The term was endorsed by Rodarian irredentists, who sought the annexation of areas where ethnic Rodarians made up the majority or a substantial share of the population: the Lusankyan Littoral, Canaro, South Gorizia, and Sistiana. Due to the Papal Republic's weakness in both economic and military terms, the claims by the irredentists could never be secured and no effort to do so was taken. However since the 1980s, claims to the Tinian March have gained attention of neo-irredentists and nationalist politicians alike. Throughout the 1980s, Rodarian culture, especially folk music produced numerous songs claiming the region as historically Rodarion. The most infamous song by Diana Cello, 'Ritorna mia terra amata' (Return my beloved land) was the most popular folk song between 1985 and 1988 and became an synonym for the struggle to return lost land and ethnic kin to the Fatherland.
The renewed attention to the Tinian March by Rodarian nationalists has been recognised as a possible focus for the instability within central Lusankya, although its connections to the Bogorian Civil War is circumspect, many commentators have argued that Rodarian support for the southern Bogorians would not have been as strong if the country was not within Tinian March, however this is disputed by a greater segment of academia and commentary. Yet the region's mythological ethno-nationalist importance has been blamed for the tensions and violence in Torchland since the collapse of the Western Confederate States in 2014.

The area's ethnic and linguistic structure
The region is comprised of many ethnic and linguistic groups, the five major groups include; Rodarians, Occidentians, Slovics, Southern Bogorians and Hellenics (Peoples with Belfrasian/Eagelander racial origins). Although Occidentians are considered racially Rodarian, their linguistic and cultural differences have enabled them to stake out an individual identity and thus are treated as a separate and individual group.
Other ethnic groups included Roma in northern Caicova and southern Bogoria, Jews in western Torchland, as well as smaller Basilerian and Carpathian speaking communities in some larger urban centres, mostly members of former Papal States élites.
According to the last census that covered a vast majority of the Tinian March, which was the Papal States' census of 1848/49, counted 978,385 people. 421,444 or 43,1% declared Rodarian as their language of daily conversation, while 327,230 or 33,4% spoke Polish, and 152,500 or 15,6% and spoke Occidentian. Numbers however would not have reflected the reality on the ground due to the Papal States' refusal to recognise the Roma language, the Slovic languages of northern Bogoria, nor Basilerian.
The Carpathian language was counted as Rodarian. According to estimates, at least 60,000 or around 14% of those listed as Italians were in fact Carpathian speakers, with an obvious pronounced separate ethnic identity.
As of 2015 however, the numbers have changed dramatically, the combined population of all territories within the Tinian March stands at 78,615,236. The population of ethnic Rodarians in the Tinian March (as of 2015) is estimated to stand at 46,688,717, which is 59.38% of all people in the Tinian March. Currently there are 3,866,728 Occidentians, representing 4.91% of the population, Slovics number 26,086,420 and 33.18% of the total population, Southern Bogorians number 5,403,580, representing 6.87% of the population of the Tinian March. Whilst Hellenics number 16,560,788 and 21.06% of the total population.
Nearly all ethnic populations within the Tinian March are found exclusively in certain locations, only the Southern Bogorians, Hellenics and Rodarians are located in different territories and states. The Southern Bogorians are found mostly in the Bogorian Christian Republic, but around 450,000 are located in Rodarion as displaced persons, many are expected to return to the BCR. The ethnic Rodarians however are found in both Bogoria and Torchland, the latter constituting the Carnaro region, smaller numbers also live in southern Iron State. The Hellenics are mostly descendants of Belfrasian-Eaglelanders and constitute the majorities in both Torchland and Iron State, however their numbers are limited by the boundaries of the Tinian March.
