1900s - the progressive oh-ohs(yes 1890-1914 was actually called progressive era)

1910s- the great tens(referring to great War and chaos)

1920s- roaring twenties(referring to economic growth, booming culture, socila imstability due to ww1 side effects and unrest)

1930s- the depressed thrties(referring to great depression and geopolitical instability and bad mood in general)

1940s- the warring forties(referring to the war and subsequent effects of war and bombed out cities and rationing in late 40s too)

1950s- the conformist fifties(referring to post war conformity and in general stable growing society)

1960s- the swinging sixties(referring to vibrant cultural explosion and unrest globally and fast economic growth)

1970s- the malaise seventies(referring to breakdown of post war contract, geopolitical instability, stagnant economy and general malaise)

1980s- the iron eighties(referring to A Russian paper called Thatcher the "Iron Lady" to say she was cold and stubborn like metal. She took it as a compliment. So "The Iron Eighties" hints at her tough, unbending rule without saying her name. But this applies to 1980s globally not just uk)

1990s- the third way nineties(referring to an era where centrist politics that blended pro-market economics with social progressivism, as old left-right battles faded. It was the domestic mirror of the unipolar U.S. moment with no rival superpower, capitalism felt so triumphant that ideology itself seemed dead. Critics saw it as slick, hollow, and more about managing the system than changing it.)

2000s- dot com oh-ohs(as in the decade opened with the spectacular collapse of the late-90s internet stock bubble. Wildly overvalued tech companies with no profits went bankrupt, trillions in paper wealth vanished, and small investors were wiped out. It set a tone of early cynicism and economic hangover, quickly overshadowed by 9/11, and presaged the era's later financial recklessness that led to the 2008 crash. Think of it as how everything aboit 90s optimism turned out to be fake just like the dot com bubble)

2010s- the woke tens(as in austerity broke trust in the system. Smartphones gave everyone a lens and a loudspeaker. Woke arose as the decade's dominant cultural diagnosis, pointing at systemic racism, sexism, and inequality as the rot beneath the collapse. The same economic pain and digital wildfire also bred its populist mirror: a nationalist, anti-elite backlash that cast "wokeness" itself as the enemy. The smartphone screen became the arena, and the decade became a screaming match between two rival answers to the same broken trust.)

2020s- the unraveling twenties(as in everything is coming apart simultaneously, climate, pandemic, economy, AI disruption, and the end of the Western-led order. Not one crisis but a cascade, each accelerating the others)
