If you mean camps run by the Armenian government the answer is none.
No, concentration camps did not exist before Hitler invaded Poland.
The key distinction was between extermination camps and labour camps ("ordinary" concentration camps).
Concealment from the local community; also to pretend that the camps didn't exist.
They did not exist. They were built during the war.
Yes, some dictatorships, such as Myanmar, operate viciously cruel prison camps for political opponents.
Key sections of Auschwitz, Buchenwald and Dachau are now museums.
they were created so jews could be sent there to "work". at the camps some jews were got sent to the gas chamber others died of starvation.
As no such things exist, there are no conditions to discuss. Palestinians have never been rounded up and placed in concentration camps and the use of that term is both insulting to the numerous people throughout history that suffered in concentration camps (especially during the Holocaust, the Soviet genocides, the Cultural Revolution, and the Cambodian Genocide) and hyperbole to inflate what wrongs Israel may perform. Palestinians live in refugee camps whose conditions while bad do not fall to the depravity of concentration camps.
Hitler decided to kill Jewish children so Jewish won't exist any more
It is impossible to accurately answer this question, although it could be surmised that other concentration camps would simply have continued to function.
The name in German is (Konzentrationslager) that means concentration camp, at first were intended to hold political prisoners and opponents of the Nazi empire but after the WW2 began Hitler use the first six concentration camps to hold and exterminate jews, homosexuals, gypsies but later he find out he could use those people for work so he created various types of concentration camps: Labour camps: concentration camps where interned inmates had to do hard physical labour under inhuman conditions and cruel treatment. Some of these camps were sub-camps of bigger camps, or "operational camps", established for a temporary need. Transit and collection camps: camps where inmates were collected and routed to main camps, or temporarily held. POW camps: concentration camps where prisoners of war were held after capture. These POW's endured torture and liquidation in a big scale. Hostage camps: camps where hostages were held and killed as reprisals. Extermination camps: These camps differed from the rest, since not all of them were also concentration-camps. Although none of the categories is independent, and each camp could be classified as a mixture of several of the above, and all camps had some of the elements of an extermination camp, still systematic extermination of new-arrivals occured in very specific camps. Of these, three were extermination camps, where all new-arrivals were simply killed -- The "Reinhardt Aktion" camps. Three others were concentration and extermination camps altogether. Others were at times classified as "minor extermination camps."
As no such things exist, there is no rationale to discuss. Palestinians have never been rounded up and placed in concentration camps and the use of that term is both insulting to the numerous people throughout history that suffered in concentration camps (especially during the Holocaust, the Soviet genocides, the Cultural Revolution, and the Cambodian Genocide) and hyperbole to inflate what wrongs Israel may perform. Palestinians live in refugee camps which were built by Arab countries that did not want to integrate them. This way, they could be permanent refugees and be a sore to be used as a weapon against Israel's legitimacy.
