This is a fantastic piece of work and very useful. I Have found it very useful even in my own family tree which covers some 200 years.

This is a brilliant piece of work, which I'm sure will never end! If you have the time and resources, consider adding in some of the recent discoveries about early civilizations in the Amazon and other regions of Brazil. Wikipedia is beginning to show some of this work, but the following is a list of sources you might invite to contribute.

Key experts on Pre-Columbian history in Brazil specialize in Amazonian archaeology, rock art, and early human settlement, including Eduardo Góes Neves (University of São Paulo), known for Amazonian studies; Niede Guidon, known for early human presence at Serra da Capivara; and Klaus Hilbert, focusing on Amazonian and La Plata prehistory.

Key Experts and Archaeologists

Eduardo Góes Neves (University of São Paulo): A leading figure in Amazonian archaeology, specializing in complex societies and landscape modification in the Amazon basin.

Niede Guidon: Renowned for pioneering excavations at Serra da Capivara National Park, proposing very early human settlement in South America.

Klaus Hilbert (PUCRS): Expert in Pre-Columbian South American history, specifically Amazonian and Río de La Plata regions.

Jonas Gregório de Souza (University of Exeter/UFPA): Conducts research on, earthwork constructions in the Tapajós basin.

Betty Meggers & Clifford Evans: Instrumental in establishing the National Archaeological Research Program (PRONAPA) in Brazil.

Update:
As I said in my earlier review, this is a great resource and I expect to spend hours playing around with it and adding entries.
The creator Adam got in touch and bent over backwards to fix my earlier problem. even providing me with a Libreoffice specific copy. Thanks Adam.

In short, anyone using Libreoffice needs to ignore the warning flag: 'Macros in this document are disabled due to the Macro Security settings.'

PREVIOUS REVIEW
It's a great idea, and the information contained is great.
However, I am constantly get an error on my Libre office, where by it opens up an objects window with an error saying "basic syntax error , symbol expected"
Every time I left click on anything to try and mark it, review it, or make the tiny writing bigger this happens.

I can't thank you enough for creating this. Hopefully more of us will engage with the past and this product will certainly facilitate greater understanding of how we got where we are.

What a brilliant idea and great work for this HISTORY TIME LINE!

I especially like the possibility that I can make my own entries.

This covers a huge range of historical events in a usefully structured but flexible way. At first, when reviewing the data by geography, I was disappointed that some important events seemed to be missing. Then I realised that there were a load more categorised by subject eg science, religion, arts etc. This is a really useful resource for a historical novel I am planning.

This is absolutely incredible, I really wish I had this when I was at school.
My grandchildren will love this.

Well done, this is brilliant!

I wish I had achieved this work as I said in title I wish I had. It is the earth's family tree and to be able your own family tree well that makes it special.

Early days - I like it!

Very extensive. Really interesting to be able to cross reference different regions and topics occuring at the same time.

– impressive collection of language and writing around the world
– family tree and map of language and writing
– mini almanac of language families (including Australia!)
– Doesn’t need macros to use
Very easy to navigate

Bought these as I like history and are very detailed and a lot of work has gone into the project. You can see births , deaths and who was crowned and who they married and other stuff. Though you see the same stuff in books this is all under one roof so no going back and forth between books.
Very interesting but love to see one of human and animal evolution.

This is an excellent resource. I am particularly interested in Greek history, and I often find myself wondering, ‘When this was happening in Greece what were they doing elsewhere, particularly in England?’ Now I can find out.

The format, as a spreadsheet, is really innovative.

It is a considerable piece of work - first of all collating all that information - and then putting it into a spreadsheet. Well done!

I've been wanting to purchase the timeline for quite some time now, and I'm happy I finally did. It's an impressive piece of work, incredibly detailed and created with so much care. An absolute treat for History lovers. THANK YOU for creating this.
