Uncover the Secret: Former Danish Capital Revealed!

As a detective tasked with unraveling the mystery behind the crossword clue ‘Capital that was once part of Denmark’, my primary focus is on analyzing the historical context and geographical connections. Knowledge of the Danish history proves to be essential, as it raises the possibility of a capital city that was once under Danish control and later gained independence. Digging further, I recall that Norway, during its early history, was united with Denmark under the same monarchy. This nugget of information could potentially be the missing link to crack the case. Delving into the historical records, I unravel that Norway gained independence from Denmark in 1814, making it a strong contender for the crossword clue. Finally, my deductive reasoning and thorough research lead me to the answer: ‘OSLO.’ Once part of Denmark, the Norwegian capital became the epitome of independence, showcasing the resilience and evolution of this vibrant city.
