This time the starting point is 1919, and it's an important one for a nation with a passion for books and literature as well as a very specific language of its own, as the first attempt is made to establish a Latvian National Library.
The century that followed brought sharply contrasting fortunes for the Library, and several changes of address, culminating in the opening of a huge new Library on the bank of the Daugava River in Rīga.
According to LTV "The Keys" series tells of the most important or "key" events, personalities and turning points in the history of the Latvian state from 1918 to the present. The purpose is to reveal each selected event from an unusual point of view, as if "unlocking the door" to lesser known and therefore particularly intriguing facts.
"Such an exploratory approach, bypassing the usual stereotypes of presenting history, will allow viewers to perceive what is known to others and to better understand what has happened in the context of today's experience," says LTV.
The show was made by VFS Films, a long-time partner of Latvian Television, and was hosted by Mārtiņš Ķibilds.
