More than three decades after Germany's 1990 reunification, lasting east-west divisions may be thrown into stark relief at Sunday's election in the eastern state of Saxony-Anhalt.

The anti-immigration and Moscow-friendly Alternative for Germany (AfD) will be hoping to win big and even to take power at the state level, which would be a first for a far-right party in German post-war history.

As much of the east has become an AfD stronghold, the government's commissioner for eastern Germany, lawmaker Elisabeth Kaiser, herself from Thuringia state in the east, spoke about the historic and cultural factors shaping the region's distinct politics.

When the Berlin Wall fell in 1989, spelling the end of the communist German Democratic Republic (GDR), many state-owned enterprises were shuttered, sparking large-scale unemployment and population flight, especially by young women.

"That was a difficult experience for many East Germans, one that has persisted across generations, becoming part of a collective East German memory," Kaiser said. "It involved this sense of devaluation, this experience of loss and the realization that everything can change overnight."

'Big disparities in wealth'

Decades on, wages and savings remain lower on average, most big business is still based in the west, and eastern Germans - one fifth of the population - are under-represented in politics.

Billions spent on infrastructure and to stimulate the economy have borne some fruit - Kaiser said the region is now home to many of the "industries of the future."

She also praised many eastern regions as ideal for young families, with lower living costs and rents, natural beauty, good childcare and excellent universities.

Nevertheless, she said there remain "big disparities in wealth" and, among many, a feeling of being "disadvantaged and not seen."

The AfD's hostility to migration resonates in much of the east, even though it has fewer foreign-born residents than the west.

While West Germany's post-war economic recovery was fueled by "guest workers," the East invited contract workers from socialist "brother states" such as Vietnam and Mozambique.

'Not an immigrant society'

They "were very much physically separated from East Germans" and on time-limited contracts, Kaiser said, meaning that East Germany "was not an immigrant society."

While state propaganda praised the GDR as internationalist, she said there was also "racism, xenophobia and right-wing extremism which unfortunately erupted in the 1990s" - an era known as the "baseball bat years" for its attacks on foreigners.

More recently, she said, resentment has spread especially about Syrian and Afghan asylum-seekers and the notion of "all the extra things they were getting for free."

Kaiser also addressed warnings that East Germany is being romanticized, a nostalgic trend known as "Ostalgie."

"In times of crisis people remember positive things from their past," she said, adding that populists were using "emotionally charged elements from the GDR era."

One icon is the Simson-brand scooter, often ridden by the AfD's lead candidate Ulrich Siegmund. 

"Back then it was a symbol of freedom because it enabled you to move around," Kaiser said.

Fearful of change

While older voters may remember feeling more secure in the GDR, Kaiser said it is often forgotten that "that was because everything was so controlled and surveilled."

She also pointed out that many in the east take pride in the peaceful revolution of 1989 and see it as proof that collectively they are "capable of toppling a system."

The AfD advocates closer ties to Russia despite the conflict with Ukraine and "hybrid attacks" Berlin has blamed on Moscow.

Kaiser said the socialization of many East Germans had fostered a "strong anti-Americanism" and a lingering skepticism of the transatlantic alliance which has not eased during the current US administration.

Many in the east are keen on renewed diplomacy with Russia - a path which Kaiser says the Kremlin shows no willingness to follow. Some in the west have suggested the richer part of Germany should stop "subsidizing" the east. 

Kaiser says she finds such ideas "disastrous" and that they "annoy me as an east German," adding that cutting transfer funds would "only strengthen the victim role that the AfD always likes to adopt."

Amid current geopolitical ruptures and economic stagnation, Kaiser said many in the east are especially fearful of change, given their turbulent history.

She pointed out that in parts of the west, the AfD and their far-left competitors are also on the rise, and said Germany as a whole should view the east as a political "seismograph."

AfD dreams

Meanwhile, Ulrich Siegmund, the 35-year-old hoping to become the first AfD state premier, has attracted packed rallies rallies in village halls and town squares across the state.

"I want my beautiful, old, safe Germany back," he told supporters.

Formed in western Germany at the height of the euro zone debt crisis, the AfD has increasingly drawn its support from the states in the east, where surveys show a lingering sense of dissatisfaction with the results of reunification in 1990.

Siegmund, who rejects the far-right label, says he speaks "the language of the people" avoiding the more extreme rhetoric of party colleagues like Bjoern Hoecke from the neighboring state of Thuringia.

Germany will be holding its breath as the eastern side of the country heads to the polls.
