question:
What criteria is used to decide when Armenia was in its heyday?, Context: The first geographical entity that was called Armenia by neighboring peoples (such as by Hecataeus of Miletus and on the Achaemenid Behistun Inscription) was established in the late 6th century BC under the Orontid dynasty within the Achaemenid Persian Empire as part of the latters' territories, and which later became a kingdom. At its zenith (95–65 BC), the state extended from the Caucasus all the way to what is now central Turkey, Lebanon, and northern Iran. The imperial reign of Tigranes the Great is thus the span of time during which Armenia itself conquered areas populated by other peoples.

question:
Why did Cubitt build the new wing?, Context: By 1847, the couple had found the palace too small for court life and their growing family, and consequently the new wing, designed by Edward Blore, was built by Thomas Cubitt, enclosing the central quadrangle. The large East Front, facing The Mall, is today the "public face" of Buckingham Palace, and contains the balcony from which the royal family acknowledge the crowds on momentous occasions and after the annual Trooping the Colour. The ballroom wing and a further suite of state rooms were also built in this period, designed by Nash's student Sir James Pennethorne.
