The flag of the "Amber Hundreds", a liberal-democratic and social-democratic revolutionary guerilla that launched numerous failed and devastating revolts against parishes, farms, courthouses, public transportation lines and governmental buildings before succumbing to in-fighting and being driven underground and quashed.

While not banned, the stigma and trauma around it has made the flag both controversial and unpopular.

• Original (pre-annexation) flags of Paraguay, Uruguay, and Bolivia, symbols of separatism
• Flag of Communist Germany (1975-1997)
• Flag of China (1949-2000)
• Integralist flag (after the civil war)

There are several other flags that Brazilians despise (the more nationalistic ones hates France for their sabotage of the space program), but these are the flags widely regarded as controversial.

In the Federation of Lillorainen, there are no banned flags, but like in most countries, some are frowned upon, among which are flags displaying symbols of fascism, communism, or any religious or other form of extremism.
Aside from these, the most 'controversial' Lillorainian flag is the flag of the Lillorainian Federal Republic, which was founded in 1948 and lasted until 1976 (de facto) or 1981 (de jure). While the contemporary Service Flag is clearly inspired by it (as both contain certain national symbols), displaying the 'original' flag of the LFR in public won't gain you a lot of friends.
For comparison ...



The LFR covered the territory of the modern States of Storöer, Sigurdsland, and Kongsöer, the Territories of Bargrade, Möngheim, Styrup, and Bordeslee (today parts of the State of Rigesöer), Southern Fyleria (today part of the Fylerian Free State), as well as the Kronstadt District (today part of the State of Thulia). The Free State of Visholm was considered an associated part, but de facto independent. Thus, it covered more than half of the territory of the modern Federation by 1970.
By 1970, the LFR had approximately 41 million inhabitants. The capital city was Nörishamn, the largest city was Lysköping.
The LFR has been the first attempt in the history of any Lillorainian body politic to establish a full democratic system by Western standards, and its history is often cited as the primary reason why the democratic experiment didn't turn out too well in the context of Lillorainen's culture and society. After the first elections in 1948, the parliament's shares were almost completely (78% in total) split up by three parties, the Lillorainian National Party (LNP), the Lillorainian Liberal Union (LLU), as well as Socialist Party of Lillorainen (SPL). The remaining 22% were shared by smaller parties, among them the Lillorainian Technocratic Union (LTU), the Regionalist Coalition (RC), as well as the Reform Party of Lillorainen (RPL). The LNP and the LLU ruled in a coalition, together making up 54.3%.
Already in the first years, it occurred to the people, that the Members of Parliament spent a lot of time engaging in ideological disputes (to the degree, that parliament brawls were not uncommon), and considerably little time actually fixing issues. The Nationalists and Liberals eventually used a loophole in the constitution to outlaw the SPL in 1951. In light of the huge popularity of the Technocratic Movement in those days, the people reacted by giving more votes to the LTU in 1952 - while it didn't suffice to actually make them a government party, it became the strongest opposition party (26.4%) against the National Liberal Coalition. The coalition quickly radicalized itself, using legal and semi-legal means to further strengthen its power. The populace reacted by voting opposition parties into their state legislatures, which, however, resulted in these serving as blocking instruments. Over the time, voters' participation shrank due to apathy, with its bottom reaching 43.2% in 1964. As a result of the powerlessness of the Nationalists, they started becoming more authoritarian, manifesting their ideology of a strong Lillorainian state, aligned with other nationalist powers of the time such as Shikonjima, Mairandra, and Ahjada, while positioning themselves against socialist and liberal powers, even those with traditionally good ties with the Lillos, such as Shamsiyya and the Moana-Nui-Islander states, whom most non-LFR states kept good relations with. After the 1968 protests in Lysköping and other university cities, the LFR soon began to use force against dissidents. As this helped little to keep the people together, the LFR went over to its last resort - territorial expansion. In 1974, they invaded the non-LFR territories of Rigesöer and Southern Nessovia, which quickly resulted in the Lillorainian Civil War.
As an aftermath, the Federation unified under the banner of the new ideology named Federative National Meritocracy in 1981, unifying all ruling parties of the Constituent National Assembly (as in, all remaining and new-founded parties) into the Meritocratic Unity Party of the Federation of Lillorainen (MUPFL), ensuring a strict competence standard of its Rulers while maintaining democratic control instruments.
Due to this failure of the LFR, symbols associated with it are usually frowned upon in Lillorainen nowadays.

The Flag of West Lushansk used from 1956 to 1993 is controversial because it was used during the division of Lushansk from 1949 to 1993 however it is not banned

Some of the controversial flags in Diarcesia are vernacular versions of the Greek letter "β" and the Roman numeral "C", which represent the warlike Castamirian Host who fought against the combined Diarcesians and Hylvorians.

The flag of the Kingdom of Adalzica, associated with neo-monarchism and support of dictatorship.

Several flags that had once been flown in the skies of Majapahit are now considered controversial; however, two of them stand out the most.

Under the 1931 Eradication of Communism Act signed by the Imperial Assembly, the flag of the Majapahit Communist Party (MCP) and any symbolism related to the ideology of Marxism-Leninism is banned from being displayed in public except for academic or research purposes. The act was signed one month after the conclusion of the Malang Emergency (1929-1931), a communist uprising driven by the MCP (and suspectedly sponsored by the USSR) in the city of Malang, which quickly spread to other parts of the Empire. The military had been quick to suppress the rebel movement, forcing them to resort to guerilla warfare which would eventually end after months of armed skirmishes.

A few decades later, the Free Atjeh Movement declared an independent Islamic Republic in the region-state of Atjeh in 1967. Once again, however, the Imperial Military was quick to respond and was able to corner the rebels into accepting a ceasefire in 1969. A peace treaty was signed later in 1970, in which the Imperial government would grant Atjeh a large degree of autonomy in social and religious affairs. The flag used by the FAM was not banned, but was instead established as the unofficial regional flag of Atjeh under the 1970 Medang Accords. To this day, the people of Atjeh had been divided on the flag issue, which is thought to have represented a dangerous separatist movement.

Some contemporary social movement flags are also considered highly controversial (such as the Rainbow Flag) as well as some state flags (such as those of Israel and Palestine).

- Nazi flag
- France Vichy flag
- Democratic Kampuchea flag
- OUN flag
- Falangist Poland flag
- UPA flag
- Ustashe flag
- ISIS flag

and some other flags of totalitarian regimes and terrorist organisations.

Using them in public, for promoting the totalitarian ideologies are punished by fine, community sentence, or penalty up to one year in prison. King Jan I is pan-slavic and fights the fratricidal policy.

The flag of the North American independence movement, particularly associated with the Sons of Liberty and the NAU Independence Party. The Sons are a right wing terror group who are anti-immigrant, racialist, anti-monarchist group that strives to violently separate from the United British Commonwealth of Nations. The NAU Independence Party is the right wing, anti-immigrant, populist party desiring to get the NAU to leave the UC through parliamentary means, though suspected to have ties to the SOL.



The flag of the Imperial Dismantlement Front, a left wing group dedicated to ending colonial empires worldwide and neocolonialism. The original flag was made by a North American university student protesting the UCN's colonial and trade policies in the 1970s. Member branches of the IDF have their flags in the opposite colours of the colour wheel, and UCN Dominions branches have the "anti-Jack" in their upper right cantons. The IDF is suspected to have a few remaining ties to the Black Jack Brigade, the former armed wing of the IDF turned terrorist group.

The flag of communist party of Novia Xeneia is banned as they have caused several conflicts within the country.
They have caused riots and violence to overthrow the government but they have failed everytime.

Waving a legion flag, legal. But it wont go down very well
It’s like waving a NAZI flag in a Jewish neighborhood
