Israeli historian Rona Sela says most of the the state’s archives are off-limits to researchers

Israeli historian Rona Sela has spent 20 years uncovering Palestinian visual history that has been kept in the dark in Israel's state and military archives. She says the methodical plunder of Palestinians' cultural assets predates the establishment of the state of Israel in 1948, what Palestinians call the 'Nakba' or 'catastrophe.'

"The looting and seizure, as far as I found, started in the 1930s in a systematic and organised manner ... by Haganah forces [Zionist paramilitary group]. The seizure intensified, of course, with the Nakba in 1948. I found materials taken in 1967, 1982, 1991 and ... in the last few years."

What begins with looting and appropriation, continues with a system of censorship and historical revisionism in the archives. The origin of Palestinian material is often erased and replaced with terminology that fits the archivist's world view.

"I saw photos with comments and notes written on them by the censors and archivists. For example, Palestinians are described as 'terrorists', as 'gangs'. Seeing all of that taught me about how the materials go through a process of rewriting to aid or benefit the Zionist narrative," says Sela. "You see a place where the materials are being censored and erased from the public sphere."
